I'm going to be dropping off my F block at my machinist to be bored, honed, whatever it needs... I've searched and found that one guy milled the block like .010, and the head at .025. I've seen others(here) that have gone .050, up to .090 on just the head. What are pros/cons of milling? Higher compression, obviously...No, I'm not racing :, just wanna pep it up alittle.
