The intakes varied from .430 to .510 net lift (.464 was legal, I think) at the retainers using checking springs and solid lifter set at zero lash and the exhaust rocker arms varied worst than the intake rockers did down
I use a old Racer Brown cheater cam on the driver side of the motor and the same pushrods and rocker setting on all of them with the same dial indicator set up on the same angles and relation ship the valve stem angles on the same head wrench
BTW, I saw 4.0 CC variance on the four combustion chambers on that head also shock


I was just about to do the same over the next cpl days, but scared of what I might find!
