    Ok on the intake and exhaust it's ok to widen them a bit. If you start to lower or heighten them it will affect you timing. After you have done a couple than you can start to play around with lowering intakes or taking some of the piston skirt, it's best to do lots of reading and studying before you play with port timing. Pay attention to places a ring can snag too, that's never good:dumb2:
