milling head 1100 stx

[rjberry]

i know his ski is old but it only has 90 hours gotta start making it faster!!!!
i have a friend that owns a machine shop he is going to mill my head. i have done research says milling .040 will give about 155 psi in tha chamber. i have found no info on the squish angle, what it is or if i should change it. what would be different if i changed it. we think it is about 8 degrees are we right? should we change it to 12? or maybe 4? does anybody know ???
