Head gasket woes

Alot of the guys running NMRA renegade are running Cometic head gaskets or Felpro MLS gaskets with their blown Mustangs.

While apart I'd have the heads looked at to make sure there still flat and not warped and causing you to blow head gaskets.

Have you had the car tuned? If so, it's strange that you would be blowing head gaskets on an N/A motor...If not, it could be part of your problem.

Please recommend your choice for a 'high performance' head gasket that won't crap out under pressure. I've blown 2 Fel-Pro 1011-2 head gaskets, and I am looking to upgrade to something more durable. The only reason I've been using them is becuase Trick Flow recommends them... why, I dont know, they are ****ty gaskets!

Photo looks real familiar. I just pulled my heads off yesterday, same result, except I'm missing about 2" of the gasket between 2 & 3. I think my problem was 8# of boost, 24# injectors & no tune. I'll be addressing all of those issues. I'm thinking of trying Felpro 9333PT-1 head gasket.

I've been told that if everything is installed and tuned properly, even the hi-po blown cars *should* be fine with the stock replacement fel pro head gaskets. It sounds like something is wrong, which is causing you to blow the gaskets, and I would recommend finding the cause. The expensive cometic head gaskets - although they are most assuredly great gaskets - are a band aid for this application, in my opinion. Eventually, you'll probably end up blowing rings next if your problem isn't addressed.

As you know, you need a weak link. If something goes wrong, your weak link will fail first. It's obviously best to make the easiest/cheapest to replace parts the weak link in the event that something does happen. Head gaskets are cheaper and easier than rings.

Spend some time and try to find out your problem and make the head gaskets your weak link. Just my opinion. Are you sure the block and heads are true? No pre-ignition, etc?
