Description: This Fel pro gasket is most commonly used and recommended for small block Olds engines with compression ratios up to 13.0 to 1. Recommended for big block Olds engines with up to 12.5 to 1. If desired these gaskets can also be used with or with out an O ring in the head. Sold in pairs.

Description: This Fel pro gasket is recommended for the 403 Olds engines with compression ratios up to 12.5 to 1. If desired these gaskets can also be used with or with out an O ring in the head. Sold in pairs.

Description: One of the best engineering inventions to date. The Cometic MLS (mutiple layer system)design is truely a superior gasket. Where other gaskets fail in being able to lock in that cylinder pressure created by hi rpm and hi compresion engines, the Cometic gasket is the answer. No O ring or reciever groove machining is required. It is recommended that the finish (RA) of your block deck and cylinder head surface be fine and smooth. Consult with us as to the RA (surface finish) required. Priced per gasket. .036 x 4.200

Description: Proven and tested both on the track and on the dyno. We have put all these gaskets to the test with various different rpm ranges and compression ratios. We run these on our own engines that have compression ratios that exceed 17.1 and better. The SCE copper gasket shown is intended for bores ranging from 4.190 - 4.250.
