Exactly.......
putting the cam in 2 retarded is going to guarantee you more retard running.

I remember Joe Sherman always telling everyone that you could run the intake clearance very close just spinning the motor around by hand. If it clears by .010 to .020 it will be fine running because the dynamic loading of the system would increase the clearances and retard the cam. The valve is chasing the piston down the hole too.
