BIG BORE HEAD AND BASE GASKETS
Big bore head and base gaskets are designed for use with overbore
piston kits. They are available in all of the most common big-bore
combinations. Big bore base gaskets have oversize holes to accomodate
big-bore kits that use oversize sleeves. If a big bore base gasket
is not listed that kit usually takes a stock oem gasket.
