well, i've got my block ready to build, now i need to order some head gaskets so i can get it together. it took a 4.540 in. Bore, .039 in. gasket on the blower motor to seal the head chamber, so does anyone make a mls, copper gasket that doesn't need a polished deck to seal against? i can get felpro mls gaskets at cost, so i was leaning that way but can't find a bore diameter that'll seal off my head.
what would you guys run for a 13 to 1 505 runnin alot of nitrous?mls, copper or cometics? non-oringed, just had the deck surfaced, but its not to a polished smooth.
