- Lets go over Cylinder head "failure"
Cylinder head failure and the root cause when you have been in the industry for 20+ years becomes easily identifiable. Today Chris talks about multiple kinds of failure and their cause along with some change with dealers in the industry.

Just wanted to let you know I really appreciate you doing these videos, it does help with siphoning thru the BS. BTW I had some m311 heads installed on my Thompson Motorsports ls427 they built us for autocross. We requested an engine that had a lot of torque! When we dynoed the Vette it made almost as much torque as horsepower! The dyno guy said he’d never seen that before and that he was thoroughly impressed and that was with a failing throttle body. I told him it must be the heads, torque and horsepower! We are still developing the Vette but just won our first race! I’m very happy with my FED cylinder heads.
Glad to hear your success and thanks a ton for the support!
Well said! that is a very frustrating situation especially with someone is not telling the whole story…
❤ ur Work .
would love to see some comparisons between frankenstein heads and other brands!
Legit PSA! I've been in this industry 23 years professionally, and I too believe that a firm stand needs to be made at times. 99% of my clientele came from unhappy relationships with their previous shops. I strive to keep my people happy, but I've held them just as responsible in the case they caused any failure.
Customer's and shops expecting a safety net for their "learning curve" and self induced components failures has been growing for decades. I just had a shop / customer call expecting a refund on an engine they destroyed on their dyno caused by an admitted lack of monitoring ignition timing during the pull. The engine was detonated to death and the bearings proved it. It will only get worse as the enthusiast thinks bleeding out on the forums is a cure for their ills.
Truth!
Hey Chris, I do have a few questions regarding opening the exhaust ports up to reduce restriction and EGTs at port itself and its relationship to velocity driving the turbo on a diesel engine. I know you’re a gas engine guy but I still listen to you quite a bit on your turbo videos. Also a few questions regarding a custom ground cam and what the minimal overlap can be and if overlapping can be reduced to zero to keep the high pressure hot gases on the exhaust stroke from interfering with the cooler compressed air charge entering on the intake stroke? Separating/Isolating the hot gases from the cooler air should help air density and improve efficiency regarding the 7.3 powerstroke with the hindering 2 valve design. I’m focused on improving that design with a few key alterations, upsizing the valves, custom valve seats with a larger ID made of better heat transferring materials, same with valve guides, also focusing on springs and retainer upgrades. I need to flow test the set of heads I ported, they have helical intake ports so cylinder swirl is an important factor for fuel atomization. I need more time to devote to the development but HVAC is very hectic in summer, and it would be nice to have a flow bench at home
Have you guys addressed the F series heads that were cracking at the lower exhaust bolt area ?
Yes sir, we addressed it late 2021. We no longer do the lightening program to keep them thick on the exhaust flange.
Just keep doing what you’re doing Chris because you absolutely can’t make everyone happy all the time trust me I have learn that after being in business for 31yr. but if you’re doing the right thing for the right reason no negativity comments will effect your business in any way !! I understand why you made this video. but just let your product speak for itself!!
Thank you!
Any chance one of these heads was on a yellow ZO6?
Hi Chris 🔥🔥🔥
Any thought of a billet Ford Coyote Cylinder head.
Definitely!!! I like carnage videos!!!.
the valves are quality valves from different company’s . the common part is your cylinder head.. it’s never good when companies defend their product.
It's even worse when a stone thrower fails basic spelling...........
When you compare stone throwing ,spelling to a possible product failure .I destroyed a 100,000 motor in a sense a LOT of carnidge
Had 2 spare valves from same order,I had a notion where issue came from in a New engine, got valves ,both fatigue tested from the new ordererd with motor. One failed,I called no admittance at all sent valve in for their testing it was going to let go the same .They take no responibiliy .I asked how was their situation in fixing the issues .They lost the valve, had the delivery postage signed for = Bad luck in so many wordsif they dont have it how would they know.
Not from these guys my failure not at all .Im thinking of using them after my issues ,is why I am watching
You get more bees with honey. Mistakes happen on both sides. Being nice goes a long way!
Thats the truth!
Just curious,does pro filer cast your heads. ?
They are LPC castings
They do not, our F Series are cast in Detroit.
@@paulferreira1603 our F Series are American made. Our doors are open if you want a tour.
@@jrgalloway86 that is true but I can tell you for a fact the M311 is based off a liberty casting
Disclaimer. If this product is used for racing. No warranty applies. There is NO product that is fool proof.
Good products, good info, but you lost me after 1 minute of that background boom boom crap.
Thank you for your knowledge and videos USA 🇺🇸 TRUMP
Are you telling me that you don't drop test your heads? Shame, Shame. :-)
We did a box durability test if that counts haha
