I got the rocker studs mounted to a junk 216 head today, and started doing some preliminary fitting of the rocker arm to valve geometry. I'll be using a lash cap to widen the footprint at the top of the valve stem, and an adjustable pushrod to determine the best angle of the rocker to the valve stem- - - - looking for a 90 degree angle between the rocker tip and the valve halfway up the cam lobe. Obviously, that will need to be finalized once a complete valve train is mocked up- - - -cam, engine block, cylinder head, head gasket, etc.
Pushrod angles will be somewhat of a sticking point, especially if the same setup is applied to a 1954-up 235 with a different water jacket. I'll cross that bridge once I have a running 216 and/or spray oiler 235 in operation and some dyno testing documented.
