[RICK LAKE]

Wrogers55 W if you are going to race this motor or 7,000 rpms and bounce it off a rev limiter then you would want no more than 1/4 turn pass contact of the 3 parts. Reason for this is lifter pump up and you don't want Mr. valve to make contact with Mr. Piston. The deeper your adjustment goes the better possiblity of a hit with a miss shift or rev limiter hit. Mine are .015" with a dial indicator on the plunger of the lifter. Have you checked the rocker postion on the top of the valves? Want to make sure that the roller stays as close to the center of the valve stem as possible. This is a good test for making sure you have the correct pushrod length also. Good luck Rick L. Ps if you are not going to high rpm the motor up to 1 turn is the normal. I would stay with 1/4 and if you hear noise from the rocker than tighten to a 1/2 turn. Be sure it's the pushrods maken noise and not the lifters or the retainer plates or bars.
