Head Shaving

[Summit_800_xrs]

Is it a good idea shave the head on a 2007 Summit XRS. I dont wanna buy a aftermarket head. Does anyone know how manny 0.001 I need to take off it? I still wanna run 91octane.

Talk to Ralph at Split Second Performance in Valleyview. He does great work and he will walk you through the theory.

I have one that has 0.010" shaved off. Where are you located? Best thing to do is to measure the squish to see how much you can go, then decide from there.
