The easiest way is to rotate the engine to fireing of no 1 and then tighten the rockers till the pushrod stops turninf freely and then tighten about one half turn, then rotate the crank 90 degrees and do the same for no 8 and so on and so forth.... hope it helps

appreciate the information. this thing is making my hair turn gray. already had to tear it down once , head gasket didn't seal. maybe it'll work this time, hopefully. never had this kind of problems before with a small block chevy. thanks again.

Bring #1 to tdc comp stroke and adjust intake 1-2-5-7 exhaust# 1-3-4-8 rotate one full turn and adjust intake#3-4-6-8 exhaust#2-5-6-7. Tighten 3/4 turn after 0 lash. There is a better description on the rbbo section that goes into more detail.
