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 oversise holes to accomidate big bore kits that use oversize sleeves. If a big bore base gasket is not listed, that kit usually takes a stock oem gasket.

Head gaskets are available in two types ; Spring steel which is an OEM style and solid copper for use on o'ring applications.

Base gaskets are available as spring steel, or copper in various thicknesses to adjust piston deck height. If you have any questions as to which gaskets are right for your application, call the APE tech line.
