You have plenty of compression to start and run. I have seen flatheads run that would not pull over 60 psi on any cylinder. The point is not that your compression is too low to run; the point is that a fresh rebuild with Offy heads should hit at least 140 lb. The fact that yours does not suggests that the cam timing of the valves relative to the piston stroke may be off a bit. That can happen if the cam gear is not correctly timed to the crank gear. That could prevent it from starting.
Are you positive you got that cam in right?
