Head shaving suggestions. Two different engines...

Post by JustynCRX »

I just picked up a 1990 SB50P and bought the tazz BBK and intake / Carb kit. Since I have to get the head milled for the bigger bore I figured I would get the head shaved too. Also I am going ti bring in the head for my Malossi SE50 kit in and have it shaved too. The SE50 is at 110 psi right now. What should I have shaved off these heads?
