If my memory is working like it should, I believe the valve setting on a 6cyl. 235 is 1 1/2 turns on the screw from zero lash. Racecarl has a post on the tech. that tells you which valves to adjust with no. 1 TDC fire and which valves to adjust with no. 6 cyl TDC fire. This by far the easiest way to adjust valves and the most accurate.
I believe the 6 cyl. engines were 1 1/2 turns and the v/8 engines were 3/4 turns from zero lash. These are all hyd. lifter settings.
