Rocker arm adjustment HELP!(Rocker stud replacement)
I have just installed a new set of crane cams energizer rocker arms in a rebuilt 327. I installed them following the instructions that came with them (When the exhaust valve begins to open, stop and adjust that cylinder's intake rocker arm and so on). But when I started the engine for the first time I had allot of tapping and a bad running engine. So I pulled the valve covers and seen that two of the rockers are no longer seated to the push rod. So what I wanted to know is if I us the method below will it help me get the correct adjustment?
Motor at TDC firing #1
Adjust #1 intake and exhaust valves.
Adjust #3 Exhaust
Adjust #5 Intake
