    Hi all. I recently got my heads milled 40thou to bump up my compression to roughly 11.1:1 but now my valves hit the top of my pistons. Cam specs are as follows 282/288, duration @.050 232/238, lift .599/.601

    What are my options in solving this problem? Any help would be great. Cheers

    Flycut the pistons
    Get new aftermarket pistons with valve reliefs
    Buy a different cam
