    760 cylinder, 701 head, what gasket?

    What head gasket am I supposed to run to make the 701 head work with 760 cylinder? Does stock work?

    Has the head been cut (squish band wise) to work with the 84mm bore?


    WHEN IN DOUBT, GAS IT!

    No because machining of the head would be against the rules, I believe.

    I would figure people are using the OEM 760 gasket and checking squish clearance to be sure.

    Use a 760 head gasket.
