350X big bore head gasket ??
i have a 452 big bore i'm putting together and i have a head gasket for a stock bore. it is metal and i opened it up a little bit in the inside bore for the bigger piston. i don't want to go any further because it seems like it would damage the sealing part of the gasket. my question is do they make a big bore gasket, or is it alright to leave the trimmed gasket sticking out a little bit into the cylinder bore? the piston doesn't hit the gasket at all.
