Im putting the motor back together in my 65 stang with a 302.Its got hyd lifters.I know the proper way is to position the valves to where there seated then tighten the rocker untill you cant turn the pushrod anymore then give it a half a turn.I did this in my stang and I tightened a few of them untill the bottomed out.I can still turn the pushrods.Lifters are new. So I think Im gonna put the motor in the car,run it untill it gets warm then adjust the rockers again.
