i agree with 4 posts above(forgott hi handle) +initially set a dry engine as stated with topof the cam-twist the pushrod - then 1/4 turn . put on both valve covers and start the sucker. THEN pull one side and usinga 5/8 socket back off each rocker until it rattles. then back it down until the rattlle stops and go whatever is you choice1/4-1/2? racers seem to like 1/4-street guys 1/2. either works..
if you have a 2101 edelbrock man. you may need an adapter to the quad. jim
p.s. they do make little clips that go on chevy rockers. these keep the oil from flying everywhere. tip--don't rev the engine with these on
