I am hoping to jump CR to about 11.75:1 Am I going to have enough PVC to mill the head to achieve that ratio with the specs on my below cam. I am also going to keep 1.7 rockers. If that sounds like too much. What would be a safe tolerance I could mill the head to still be ok on space.

Thanks

IMO with that cam you'll need fly cutting.
But first what heads? LS1's?
Because with an LS1 you'll need 57.39CC for 11.75:1 and even with stock valves you'll flycut.
Probably ~ 10.5 CR would be your max (estimate)

Well you see and thats why I asked. I was thinking that a 62cc ish chamber would be close to there, guess I was a bit high. I kinda figured with my cam I am looking at having to flycut. Yes they are LS1 heads. So are you saying at that I would have to stop at 10.5:1 for no flycutting? I would assume that you dont mean 10.5 would be my max period. How much of a mill, in decimal would it take to get to like 11.25:1? I am not good with all these equations for internal measurements, but I am trying to learn.

Thanks
