ask for "Rock" gaskets when you order from Enginbldr.
Personally I have a machine shop locally that does all the drag and circle track engines around here. they can order my parts from whoever i choose and can machine a block like nobody else ive seen.
so if you have a race track near you find out who builds there engines and go there. dont bore the block over .040, if you do you will have a hard time finding good pistons.
