I guess I have a blown head gasket and wanted to know which one to buy if I am going to run boost?
I have white smoke coming out of me tail pipes and no compression on #2 & #8 cylinders
How serious is the combo? What's the engine? charger? how much boost? Believe it or not a lot of people actually run junk stock style fel-pros to act as kind of a fuse. So if it detonates bad or something hopefully you lose a head gasket rather than pistons, etc. I'd rather swap a HG than bottom end and who knows what else gets taken out. There's a lot of people on the turbo forums making huge power with junk HGs. You shouldn't have a problem if it's tuned well.
The correct # is 1011-1, but those are a popular gasket that seem to hold pretty well. There's also the 1011-2, which has a copper ring instead of steel. I've heard a lot of good things about the 9333-pt2 gaskets too, that's what I'm trying.
Regular Fel-Pro 9333's hold up just fine under boost. Tons of people run them at 15+ psi and I know of someone who went in the 8's using those headgaskets with over 25 pounds of boost. It's all in the tune. If you run those metal Cometics and your tune is off, your gasket may hold up, but you may end up replacing pistons instead. Always better for the gasket to let go than the bottom end. Use regular gaskets and get the tune dead on and you shouldn't have any problems.
Hey guys thanks for the info. It's just a 302 with a trickflow H/C/I. I'm only going to be running around 10psi with a vortech and a aftercooler so nothing extreme.
NO! I would high suggest to stay away from Cometic head gaskets. I ran them on my stang they leaked water into the exhaust valve. So my exhaust was steaming. Just do a google search about cometic gaskets and their problems you'll find they aren't worth running.
Also their customer service is horrible because when I called them to tell them what happened they told me there is nothing they can do and they are having "quality issues". Do you want to purchase a product that the own manufacture doesn't stand by?
With that being said depending on how powerful your setup is going to be. The way I see it I'd rather have the head gasket fail before anything else. I used Fel-Pro 1011-1, I am not running any boost yet but I don't plan to run more than 12 psi. That'll get me far enough into the 10's for now...
