push rod length

This is wide open to a slew of questions.

Was the block or heads milled and if so, how much?

What head gasket are you useing?

OE Hyd. Rockers or Mecanical ones?

On the cams base circle, the pushrod must depress the lifter a min. of .020 with the rocker gear on, set up if mechanical and of course, valves seated closed.

I am not to happy with .020 as a min. and would rather set it up to depress the lifter approx. .050 downward. That would put the set up right about where the factory set it up for.

The lifter has about .100 movement with the last .010 not really useable. That amount isn't what you can push it downwards with your hand, just the way it is supposed to operate.
