I have a -6 head that may have never been cut down and heres the rub.I have 
read lot of mail from guys haveing there heads cut to get 9.5 to 10.1 CR,most 
have to have .100 to .135 taken off to get to that point,I just got mine back I 
told the shop doing the work that I wanted a 45cc chamber and would prob need 
something in the .100 to .135 taken off.Shop forman tell me that to get TO 
45ccs,they had to remove .170 from MY head,have I messed up,or WHAT.Comfused
