has anyone tried shaving the head to raise the compression ration to say 9.0:1 instead of the stock 8.5:1 could you still run 93 octane without detonation????? has anyone done it and have dyno numbers??????? if running stock cams will you push the valves into the pistons???????

I dont think you would want to do this on a turbo car......

I would only do that if I didn't have any plans for larger turbos. Stock twins with more bottom end.
