Need a 4G64 head gasket that supports high HP
I need a GOOD head gasket for my 2.4 LR that will support 900hp, 40-45psi of boost.
I searched and searched.
I finally came across this one from ND. Has anyone tried it or know of one that works with high boost?

Some mentioned stock 9 gasket thats bored out but where do you get those?
Update: Found Buschur can get the OEM Mitsubishi 5 layer IX head gasket, bored out for a 2.4 and thats the route I'm going.

These feature and conventional layering system and an EXTRA WIDE stopper sealing fold, these can be used with NO wire ring on ALL 4G64 builds and hold up to 900Hp.

2nd on where to find bored out stock gaskets. Nobody sells them anymore. As for the MLS 4g64 gasket, I've heard people using them and having decent results. but nobody in detail....

Yep, its frustrating. I'd be curious who is making 800+ hp on one.

Many have hit 900+ without o-ringing the block/head. I know my buddy Jake hit 1100hp on an engine dyno with his 2.1 with a Felpro permatorque running 50psi and no o-ring. He had a batch made from Felpro. Maybe if we can get enough orders, Felpro could make a some. I have read Cosworth is actually Cometic but I'm not sure if there's any truth to that or not.

I have this one as MAP pretty much said this is the one to go for with my stage 5 head and stage 2 block 2.4LR. This thing is solid compared to any other head gasket I've seen. Max boost I'm running is going to be 35-40psi. I'm not o ringed at all, but its pricey lol

Any modified stock headgasket that cuts into the fire ring is not "perfect" and will fail. The PE has proven to be susceptible to failure by misfires and is alot more sensitive than the Cometic. Every PE equipped car we have done with the exception of one, has had an issue. We have gone to the normal base Cometic. It seals our drag car making over 1050whp, it seals my car at 794 and is now in Mikeys.
Remember the key to advice on the internet is take it from people that do it on the daily and have these motors running and going through abuse. If somehow all my data was incorrect when I tested my car on pumpgas and the car was knocking like a son of gun, the first thing that should have gone was the "cheap" headgasket. It was and is fine

Thats what MAP suggested. I'd like to see who with high 800+ hp is running one.

I'd be curious how that gasket holds up with 40+ psi of boost.
Magnus suggested running the HKS gasket but thats not cheap. I don't mind paying for one ***IF*** it will hold. Felpro does make a gasket for the 4g64 but its half as thick as the stock 8/9 gasket and I don't think I want to take chance with piston to valve clearance.
