best head gasket
 

what is the best head gasket to get 4 my 88 turbo? I plan to run apx 500 hp and I was thinking of a 3mm bead gasket.

A stopper type would be more reliable and just a bit more money. I would go with the stopper type. HKS makes a good one for about $400.

you don't just throw out a number


you need to think about it and figure out how much your head has been surfaced already ,
if any
and what your current compression is and what you want in the end
whats the block like has it been surfaced
