If you already have the heads off, then use some clay and check the intake and exhaust valve clearence to the piston before you install a cam with .480 lift or more, especially if you plan to use 1.6 rockers. Its a quick check and it could save you a lot of broken motors later. Valves don't get along well with piston tops and when you increase durations, they get closer without changing lift. Food for thought?
