Most 224 cams are in the 7.400 area with stock style heads, vavle angle etc.
Best to look around for a dial indicator with vice grip base?
Find a cylinder that is on compression or vavle that has no lift acting on it.
Install a 7.400 PR; tighten the rocker arm down till it has no play no preload (zero lash) zero the dial indicator and tighten down the rocker as you would normally, when tight the number you obtain should be .040"-.080".
If the number isn't .040"-.080" you will need corresponding length pushrods to obtain the ideal preload number.
