    12.5:1 are you running race fuel I hope? Also your head is shaved, I would assume that would bump up the compression ratio a little higher than 12.5:1. I know that you have a Wiseco piston that's 12.5:1 but with the head being shaved it would bump compression up and then what it be? Anyways my point is that if your not all ready running a race fuel or running to low of an octane this is were some extra heat could come from.Oh yeah jetting is another big factor as well, but I'm no jetting expert so tell us what your running for jets now and someone will chime in and help you out good luck.
