Be sure to check for sufficient rocker arm-to-valve spring retainer clearance, rocker arm-to-stud boss/hex clearance, rocker slot-to-stud clearance, pushrod-to-head clearance, pushrod cup-to-pushrod tip clearance, oiling hole alignment, and for sufficient thread engagement of the adjusting nut. Of course do a piston-to-valve clearance check throughout the cam cycle too, and also check for rocker arm-to-valve cover clearance. Correct any clearance issues by machining.
