I am thinking about running the gm mls style gasket, i have heard that peaple are having problems with cosmetics under boost.
i am going to be runing about 10 to 12 psi i have a set of wisco blower pistons that are 3.905
will i still be able to run the gm mls gaskets with this bore size?
is there somthijng else you recomend besides the gm's?
i will be running either ARP studs or bolts
most likly studs if i can budget for them
thanks for any help

 

Cometics are excellent, as long as deck and heads are flat and clean. Used same set on afr heads on vette in sig, no issues. Granted, N/A but you'll be fine with 10-12 psi boost. Plus, you can order specific hole diameter and thickness from Cometic also.

 

I used some copper spray on my cometics

 

Agreed on the Cu spray
