I prefer Cometic, I am using them on my boosted car. They are multi-layer steel, and come in whatever thickness you need. Pics here:

+1 for cometic, i have them, you have to make sure that the block and heads are very very clean, must be almost mirror like shiny, and spray them with some copper tack sealer, i forgot to do this and i had seapage between the block and heads, used some bar's leaks head gasket repair and it stopped the leak.

any part numbers?

Cometics are not for "good enough" tunes. It will be your heads and internal parts that pay the price for detonation as opposed to the gaskets.

+1 Cometic for boost!! Make sure the RA finish on your heads and shortblock are per Cometic's standards. The finish on both should be as smooth as glass.

The part # is H1296. Ford 302/351, 4.100" Round Bore, .040" MLS Head Gasket

what do you mean i know stock gasket get blown with boost

What Dagger is saying is that since the MLS style gaskets do not blow out you trend to do damage to the internals and the valve train. I won't put a Cometic on a customers motor who doesn't understand this or have a good understanding about tune.

I use a lot of Fel-Pro 1011-1 on boosted combo's well into the 15+ range without issues. It is all in the tune.

Like mentioned the MLS style gaskets require a very smooth finish, I can't recall the RA number off the top of my head. I use a Chrysler MLS gasket spray on all of the MLs gaskets I use to prevent sepage/leakage, it works better then the copper spray.

 

[aleborjas]

can i use felpro-1135 shining up all the surface for a supercharged engine and i can spray some glue permatex or something!
