Im TRYING to adjust the intake/exhaust valves right? well i wanted to know if they open/close in firing order sequence. because when i got the #1 cylinder done i assumed the next one would be #8 but my eyes saw the #3 cylinder valves move(). is that normal? Im adjusting them 1 cylinder at a time. shouldn't it be 18436572?? please help this car makes my head hurt.

 

they will all move on different strokes at the same time.. the fireing order is18436572 in the gen1 small block.. there is 90* of rotation in a gm small block (marked on balancer) If the marks don't go to 0* your not at TDC(Top Dead Center)

 

OK so then its normal. thanks.

 

the easiest way to do it and for sure is with the engine running there are some videos on youtube, at least in my opinion thats the best way to know that theyre adjusted correctly.

 

ok im still having a problem. after adjusting #1 cylinder #8 valves are not moving when im turning the engine. and i can't start the engine unless the valves have some kind of adjustment already on them.

 

If you want a really easy, no-thinking required way to do it, slack all the rockers way off, then line up the marks at TDC. Adjust all the rockers so that you've just taken the slack out of them. Turn the engine 90 degrees, then check the rockers again and adjust only the loose rockers so that you've just taken the slack out of them again. Repeat this, turning the engine 90 degrees at a time and adjusting only the rockers which continue to be loose on each pass, until you've turned the engine through two full rotations, and there are no more loose rockers. Then give each nut about 3/4 of a turn more. It might take a little longer, but you don't have to keep track of which valve you're about to work on next.
