    750 ZXI Heads

    Can you gain anything by shaving down the head on a 750 ZXI by .020"-.030" or not, thanks.

    That is a very open ended question. What else have you done? What fuel are you running/planning on running?

    Yes the added compression should help you get more power, but it really depends upon the other issues.

    If you do you will need to reshape the dome or run race gas. If you reshape the dome you will only need 93 oct. You will need to adjust carbs as well or you will hole a piston real fast.
