rocker arms adjustment

I agree. 1/2 turn at the most. I just put a set of Proform rorkers on my
340. Made sure the lifters were all the way down in the bore. Rotated the
push rods till they were unable to turn. Gave the rocker adjustment another
1/2 turn. and tightened down the jamb nut. Fired it up and it ran great.
Good luck, Green Duster.
