be careful with getting the head shaved yes it will bump the compression but will not allow you to run as big of a cam.

I'm guessing he means valve to piston clearence. When you shave the head, you bring the valves closer to the pistons. With an aggressive cam, you run the risk to the two colliding, killing your motor.
