FWIW...I have a new set of Cometic gaskets that I will sell if anyone is interested. P/N C4264HP, Thickness is .043" with a compressed thickness of .040". I will let them go for $110shipped.
Reason for selling? They're making me a set of .027" gaskets to run around on......
If you're going turbo, they'll make you a set of .060" gaskets or even thicker if you want. Call Kevyn at 440-354-0777ext.120 and tell him Jay from Sourcemotorsports sent you!
