I know this has been discussed over and over again. I set my lifters with the engine off and in # 1 cyl. there is half of the lifters ( valves ) set, then I turn it 1 more revolution too # 6 and set the rest. Now once you are in one of these here cylinders firing wether it be # 1 or # 6 how far do you tighten down your set screw once you have determined no wiggle or rotation of the pushrod? I have heard 1/2, 3/4, or 1 full turn. My 235 6cyl. has a bout 60,000 miles on it.
