My friend, you are going to need a manual for that.There are torque spec's as well as sequence information in there.........I wouldn't use information from "yahoo answers" on something as precise as that. GET THE BOOK...YOU"LL BE GLAD YOU DID...HAPPY WRENCHING!!!!

With the valve closed tighten the nut until the rocker is touching the valve stem then go another 1/4 turn. U will have to rotate the engine over by hand or use a starter button to rotate the engine over take your time do one valve at a time.

You back off on the nut until you hear a tapping sound. Therafter, you tighten up slowly until you hear it stop. Then, make a 1 +1/4 tightening turn to secure its position.. Repeat for all the others. . . To be more accurate, you can buy a chevy engine maintanence manual for the year model of your engine from a qualified automotive dealer.

with that particular valve closed, while spinning the push rod, tighten the nut til you cant spin the pushrod and then go another 1/4 turn.
