On a stock Gen II, pulling and CNC porting the head with different cams would, I assume, offer additional benefits when properly mapped on a dyno.
What about simultaneously milling .020 thousanths or 1/2mm from the head to bump up compression and run hi-test at the pump?
Is there enuf meat on the head to do that? Any possible valve to piston issues with that?
If .020 were removed from the head, with the stock bore and pistons, how much would compression be bumped? 1/2 point to 13 to one?
You math guys know and you engine guys know how much can be safely removed without issues.
I don't.
