No problem, I figured I'd help Tim out with yalls mice problem lol since he helped me with the purchase of his supercharger back in September. He's a good dude. Will certainly be using some of them hi-perf MLS head gaskets that you're talking about real soon.
Cool video! What's your take on installing a Range Technology DOD delete module to disable the 4 cylinder mode, to avoid collapsing lifters on these Chevy 5.3 V8s? Thanks. :)
@@chrisspeer990 I doubt it was a deliberate design. If that was the case why did they make replacing lifters which is more common than changing a cam require taking the heads off?
@@sexyfacenation Iam talking about a racing application for example like when you're at the track I'm not talkin about if a lifter where to go bad or a cam were to go bad I'm talking about if you want to do a Fast cam swap you can do it .the ability do it was no accident or oversite on gms part careful planning went into the Developing of the LS series motors becuse gm knew the LS motor was going to have big reputation to live up to as well as now was the time to fix the faults of the old school motors not that there where many.lol
if you hear some ticking coming from the engine ,remove the valve covers and check for any loose rocker arm ,and loose push rods .if you find little needle bearing during a oil change ,you mite need new rocker arms or lifters .
This happens because the lifter trays wear out and the lifter starts to turn in the tray and hats what causes the lifters to fail and ruin the cam at the same time. Always install new trays.
One of my valve cover grommets crumbled and fell in the bolt hole underneath the rocker arms, any idea where that leads to? It was the third bolt hole on the passenger side of the block
Ken, if it was a head bolt hole, it goes through and ends up in the pushrod/lifter bucket area. This could definitely be a problem.

Hi one quick question so do i torque 1-15 at 22lbs and the go back 90deegre and 70degree? or are the m11 bolts first and m8 bolts last? pls help thnk u..
I can not find the loosening sequence for the head bolts! I know this is important to avoid warping the head or the block? Can you please divulge this information for me?
I've done dozens of heads and never had leaks or fails from using the roloc brisle discs to clean aluminum and iron blocks and heads. Not to say it's best, but unless you cut deep to try to get rid of any corroded grooves, it is not a problem. The problem is when people clean too much.

Is there a such thing as using the wrong head gasket cause I installed some and now I got white smoke at startup and hesitation on my 2007 Ls I need help!!
The head gaskets are directional (front to back). If installed backwards, coolant flow could be restricted. This would cause the engine to run hotter. However, we do not think leaking (both internal or external) is prevalent. The white smoke at start up (if antifreeze/engine coolant) could be related to a coolant leak. You could use a pressure tester on the radiator to see if there is a leak.
Keith, you can find the sequence at www.fme-cat.com/torqueTableWindow.aspx?a=56342&s=922. It is the same for all the LS engines but we did not know if you are using stock head bolts or ARP bolts so the torque specs may not be right.
Manufacturers use aluminum heads for the benefits of weight savings and heat distribution. Aluminum is a better conductor of heat and allow manufacturers to run higher compression ratios which make the engine more efficient.
The longer head bolts (early design) are for 2004 and back engines. The shorter design head bolts are for 2004 and later. Always best to check the catalog for the correct bolt set.
The LS engines use a T-T-Y (Torque to Yield) head bolt. In a nutshell, this bolt (once torqued) is only able to be used one time. So any time the cylinder heads come off, the bolts need to be replaced. A torque to yield fastener (TTY) or stretch bolt is mounting hardware in the form of a fastener which is torqued beyond the state of elasticity and therefore undergoes deformation, causing it to become permanently elongated. Once removed, the bolt will need to be replaced.
This guy's talking to the audience as if it's going to be a home job first of all if it's a home job you need to send it to the machine shop to check that it's not warped cracked Etc so they have a machine that cleans it anyways if you don't send it to the machine shop to get it checked even mil for better compression you have no business building the motor in the first place when I do my Motors I put it in my sandblaster and it cleans the head anyways then I put it in my Engine Cleaning Oven Ultrasonic Cleaner Spraywasher anyone is good
I dont really know anybody who sends their stuff to a machine shop. Everyone I know who builds circle track race motors just tests for cracks with a liquid test kit

You can also place a line at the 12 O clock and turn to the 3 O clock position. Free and simple 90 degrees
This was great... thanks for sharing, Im not new to the business but new to ls engines and this was a big help to me for some upcoming work. thanks!!!
This is a great video for reference let me just say that!
Been using cookie disks for years on auto heads and water sports heads, never had a problem......
you need 160 180 RAs for the gaskets to seal .
Yeah agree here. As long as you don't go crazy with the pads I don't see a problem
Carb cleaner and a sos pad works just fine without damaging the head
Cool video! What's your take on installing a Range Technology DOD delete module to disable the 4 cylinder mode, to avoid collapsing lifters on these Chevy 5.3 V8s? Thanks. :)
Could you use a performance gasket on a reg. Application
Does the drop of oil on head bolt apply to LT engines also?
Thank you for the video.
Great video! I'm about to replace the head gaskets on my 5.3 Vortec.
Boston Joe 620 how hard was it?
dont need to remove heads to pull cam, disconnect rockers and spin cam a few times and lifters will be pushed up into the retainers.
He says camshaft and lifters many times. So that's head off bro
@Dansyoutube what op said is correct but not really relevant when replacing lifters though is it?
That is things gm designed into LS motor to be able to swap out cam with out pulling heads

What do you do if you get a oil on the gasket from your hands or the head leaking out how to clean it
if you hear some ticking coming from the engine ,remove the valve covers and check for any loose rocker arm ,and loose push rods .if you find little needle bearing during a oil change ,you mite need new rocker arms or lifters .
What gasket do I need AFR 215 cc aftermarket heads for LS1
What website is best to buy parts and or engines?
This happens because the lifter trays wear out and the lifter starts to turn in the tray and hats what causes the lifters to fail and ruin the cam at the same time. Always install new trays.
New OEM trays aftermarket types are known to fail
I replaced head gaskets and has heads shaved. My rear cylinder on the drivers side reads 700 degrees....twice what the rest read....any ideas?

M11 first then M8 last, torque to 22ftlbs from the middle to out in a spiral pattern
Omg did this guy really just put the head bolt in with a impact gun......
What about iron heads / blocks .
Thanks , :-)
Wyr
Why???
I can not find the loosening sequence for the head bolts!
I know this is important to avoid warping the head or the block?
Can you please divulge this information for me?
Same pattern as install. Start in the middle and zig zag outward.
Iv already cleaned all surfaces with the plastic yellow disc. Im i ok to install the head or is it to messed up at this piont?
I've done dozens of heads and never had leaks or fails from using the roloc brisle discs to clean aluminum and iron blocks and heads. Not to say it's best, but unless you cut deep to try to get rid of any corroded grooves, it is not a problem. The problem is when people clean too much.
@@SGaryNinja i ended up taking it to a machine shop to have him look it over.. He said everthing was fine. Nothing to worry about.

Yea you can definitely use the wrong gasket. Gaskets are vehicle specific.
The head gaskets are directional (front to back).
If installed backwards, coolant flow could be restricted. This would cause the engine to run hotter. However, we do not think leaking (both internal or external) is prevalent.
The white smoke at start up (if antifreeze/engine coolant) could be related to a coolant leak. You could use a pressure tester on the radiator to see if there is a leak.
Need some close up shots
What is the bolt sequence
Keith, you can find the sequence at www.fme-cat.com/torqueTableWindow.aspx?a=56342&s=922. It is the same for all the LS engines but we did not know if you are using stock head bolts or ARP bolts so the torque specs may not be right.
Why do we use aluminum heads today if they're so delicate?
Manufacturers use aluminum heads for the benefits of weight savings and heat distribution. Aluminum is a better conductor of heat and allow manufacturers to run higher compression ratios which make the engine more efficient.
@@GarageGurus Very interesting, thanks!
a good machine shop will straighten an aluminum head not mill material off of it
Paint thinner plus a non metallic scraper will remove all of it.
There are two types of bolts which one goes where
The longer head bolts (early design) are for 2004 and back engines. The shorter design head bolts are for 2004 and later. Always best to check the catalog for the correct bolt set.
By forgiving you mean incapable of damaging the head
Is there any difference going from ARP bolts to studs
different torque specs and procedure for the studs
steve nash studs are “better”
You did not explain why the bolts cannot be reused.
The LS engines use a T-T-Y (Torque to Yield) head bolt. In a nutshell, this bolt (once torqued) is only able to be used one time. So any time the cylinder heads come off, the bolts need to be replaced.
A torque to yield fastener (TTY) or stretch bolt is mounting hardware in the form of a fastener which is torqued beyond the state of elasticity and therefore undergoes deformation, causing it to become permanently elongated. Once removed, the bolt will need to be replaced.
It’s self explanatory. TTY
Probably a $500.00 + torque wrench ? I would like to have one of those but as a DIY i just cannot justify the cost :(
If you do it yourself. If you can't you pay
Imma let my wife work on my head later on she’s excellent at head work.
Yes, many men already know that. Currently and before
You over torque the first step with the gun.
Dont remove the head like he did slamming it on the dowels..and in the real world you can reuse the head bolts..
