Yes, 3/8 - 24. They will be tight because the rocker screws are made to be tight. You can run a die over them if you really want them looser.

Thanks fellas,now maybe I can keep a good lash on this engine.
I know that I should probably get shorter push rods but this is the last season for this engine and probably the last 170 Ill build for a while.
Thanks again
