You mentioned your " Head Oven " in regards to the 300 inch Ford head being twisted and warped . Can you expand on the head oven and how , if the head fit it , the oven could be used to un-twist the thing please ? , Appreciate it , thanks .
I had a few 300 6 cylinder engines rebuilt years ago. Had to go back and put hardened exhaust valve seats in them. Exhaust valves were sinking. Also replaced the older head with the newer version. Got better MPG.
i'd like 2 bet.."a lot" of them come right from the factory (Gm,Mopar,Ford,etc.) less than perfict..!.they know what they can get away with..!..thats y..if u get Quality work done by a builder or machine shop...the motor is better than when it left the factory...!..no way any of the big three can take the time on each part...like u just watched...!..good video Daniel...thanks..
You haven't talked a lot about guides, at least not from I seen. Do you prefer guide liners or core drill the guide and install a cast iron guide? I've had guide liner equipment for decades in my home shop. A few years ago I had a lisle 59000 valve guide tool to drill out and replaced valve guides. I haven't tried to use this set yet but i wanted to know whether you prefer to use guide liners or to drill and replace the guides?
Gotta say, your machining/business/wisdom content is on point sir....but....my question is...do y'all do the head cleanup every day? The hair/beard is always on point....good all around! lmao
At what depth of a "soup bowl" would you toss a head or be forced to put it in the oven to straighten? I would like to see the oven and straightening process and the cost involved? Thanks for making us a little smarter!
On my Chevy I6 292 I'm running an aluminum Falconer V-12 head with a 6-71/nitrous so this doesn't apply to me but it has been discussed for a while. Old man Gaerte "Gaerte Racing Engines" told me before he passed away the removing the bolt bosses on an iron Chevy I6 head to install "lump port" inserts in the intake ports weakened the head and caused warpage. What are you views on that? Thank you for your time.

I'm guessing the manifold side of the head is also warped. Will you surface it too? And what about the intake and exhaust manifold mating surfaces? Just watched you assemble the head, I guess not. Thanks for the videos!
Was headsanded i seen lod shop have a table that had grind stone and you use the table on side look under and after sliped filler gage tell you lows crude
Rookie question: wouldn't it be better to start the machining from the low spot in the middle of the head - work towards one side, then reverse, or doesn't it matter?
@@user-hb2gh6wh7e I get that, but we already know before starting how low the spots are. We don't need to begin the first cut at the bottom, but at the same first cut height - just start the cutter at the low spot instead of off the deck. My thought process being it might be easier on the cutters, but in any case, the answer is that the machine doesn't work that way so the question was moot.
@@ohger1 Think about it. If it were possible that you could start at the low spot then the depth of cut at each end would be full height or all the warpage on the head. Don't think the cutter or the machine would like that. The owner of the "cheap" machine would not either. So that is why little by little from end to end. Retired machinist/mechanic.
Good info. So if the head were to be installed without machining it, would it "twist" itself flat when the head bolts are torqued? Not the right way, I know that, but just curious.
That's a lot of thickness of metal that you are hoping to flatten out as well as twist. Look at what the head gasket (and vehicle) manufacturer say about head flatness requirements. Retired machinist/mechanic.
Then the chamber size for this head doesn't matter since the ends of the head had more taken off than the inner chambers and it is not for performance?

I could watch your videos for days bro. I've learned more from you than my 45 years has ever taught me! Thanks for the videos!
very welcome!!
Keeping the shop clean is the hardest part.
Absolutely
My 1966 300 was fairly twisted up when it blew the head gasket like 3 years ago, 20k miles
Love the upkeep and the cleanest of your shop keep up the good work
Thanks, will do!
I like the 300's. I got one out of a 96 I wish I had the money to send it to you for a good going over. : )
_Good Grief!_ . . the size of those 18mm spark plug holes always shock me a bit.
Definitely
If you think that head is long, you should have seen my 1952 Nash Ambassador straight 8 that I owned as a teen.
Definitely
I have heard with the straight six cylinders it is important to untorque the headbolts in the right order to help stop the wraping .

We use liners a lot, they are great
have you ever thought about doing a 'shop tour' video?

Ever 14 days, like click work!
Love to see how a head is set up and squared in the milling machine.
Definitely
How did it not kick head gasket being that far out
You would be surprised how good a composite gasket works
Composite gasket and no real cylinder pressure
It's entertaining to watch a master at work!
Ty!!
At what depth of a "soup bowl" would you toss a head or be forced to put it in the oven to straighten? I would like to see the oven and straightening process and the cost involved? Thanks for making us a little smarter!
Wonder what happens to flatness when you bolt on the manifolds? Will you flatten the manifold face as well as the manifolds?

Running? Have you got it bolted on completely yet?

Wish these guys would wear safety glasses!! 😢
Hey guys I have a 2jz with DOHC what do you mean when you talk about straightening the cylinder head first?
Rookie question: wouldn't it be better to start the machining from the low spot in the middle of the head - work towards one side, then reverse, or doesn't it matter?
The machine only works one way
The low spots are too low to start with. Every pass (x-axis) is at a given feed-rate, with a given depth (x-axis).
@@powellmachineinc3179 Thanks - as I said... rookie.. 😅

Wouldn’t the bolts pull the twist out when tightened
Some, but not all
to some extent. there are only 4 bolts per cylinder so a lot of warpage occurs.
Then the chamber size for this head doesn't matter since the ends of the head had more taken off than the inner chambers and it is not for performance?
No, it's just a very negligible amount, it takes. 007 to make just 1 cc, so it's a moot point, the cast chambers vary more on there own
How often do you see an ls valve pull in half when you put the. 600 lift cam with 160lb on the seat?
I would never have 160 seat with a .600 lift cam unless it was a turbo deal with 25+ psi
But... I have only seen a couple come apart, but we ONLY use 1 pc valves in performance applications
@@powellmachineinc3179 I dont run that much boost. You think I ought to rethink the situation?
@@davidreed6070 why would you need 160 on the seat?? where did you come up with that #
@@powellmachineinc3179 I got the spring that came with the cam and set it up as instructed.
How much can you cut per pass when your ruffing in.
More than I want to, probably. 030 or so
Was the manifold-side warped?
Very little
Just thinking, straightening out a head might make an interesting video. Or too boring for you?
