Small Block Chevy Valve Adjustment Order 0 deg TDC, both number one valves shut.

Adjust the #1 exhaust valve

Adjust the #1 intake valve

Adjust the #3 exhaust valve

Adjust the #5 intake valve

Adjust the #7 intake valve

Adjust the #2 intake valve
Adjust the #4 exhaust valve
Adjust the #8 exhaust valve
Now rotate the engine 360 degrees. The mark on the balancer should be back at the TDC mark. Keep in mind that this is not the TDC where #1 would be firing! It's where #6 would fire.
Adjust the #3 intake valve
Adjust the #5 exhaust valve
Adjust the #7 exhaust valve
Adjust the #2 exhaust valve
Adjust the #4 intake valve
Adjust the #6 exhaust valve
Adjust the #6 intake valve
Adjust the #8 intake valve
This should be what you need.

I use this method - it's guick (not need to worry about TDC) and it assures lifters are on the heal of the cam during adjustment:

Intake Valve Adjustment:
with #1 cylinder Intake Valve at full valve lift .... Adjust #6 Intake Valve
with #8 cylinder Intake Valve at full valve lift .... Adjust #5 Intake Valve
with #4 cylinder Intake Valve at full valve lift .... Adjust #7 Intake Valve
with #3 cylinder Intake Valve at full valve lift .... Adjust #2 Intake Valve
with #6 cylinder Intake Valve at full valve lift .... Adjust #1 Intake Valve
with #5 cylinder Intake Valve at full valve lift .... Adjust #8 Intake Valve
with #7 cylinder Intake Valve at full valve lift .... Adjust #4 Intake Valve
with #2 cylinder Intake Valve at full valve lift .... Adjust #3 Intake Valve

Exhaust Valve Adjustment:
If you have noticed, this is the same procedure as the intake valves listed above, just that you are now adjusting the exhaust valves the same way.

with #1 cylinder Exhaust Valve at full valve lift .... Adjust #6 Exhaust Valve
with #8 cylinder Exhaust Valve at full valve lift .... Adjust #5 Exhaust Valve
with #4 cylinder Exhaust Valve at full valve lift .... Adjust #7 Exhaust Valve
with #3 cylinder Exhaust Valve at full valve lift .... Adjust #2 Exhaust Valve
with #6 cylinder Exhaust Valve at full valve lift .... Adjust #1 Exhaust Valve
with #5 cylinder Exhaust Valve at full valve lift .... Adjust #8 Exhaust Valve
with #7 cylinder Exhaust Valve at full valve lift .... Adjust #4 Exhaust Valve
with #2 cylinder Exhaust Valve at full valve lift .... Adjust #3 Exhaust Valve

Is this a new or rebuilt engine???
If new or rebuilt, do the preliminary adjustment as stated by the guys in the last posts if that suits you.
If it is an engine with some miles on it(being ran and driven at all),remove one valve-cover and either use the anti-splash clips on the rockers.You can get them at a local auto-parts store for about $10.00.Install the clips on the rockers and with engine idling and warmed up to normal operating temp, start with # one rocker and slowly loosen the adjuster nut until you start to hear it clicking.slowly tighten the adjuster nut until the clicking goes away. then SLOWLY turn the adjuster nut 1/2 turn tighter.You are done with that rocker. do the same to all other rockers one at a time until you are done with the last rocker. install and secure the valve-covers and your valves are now adjusted cool
I never have used the 1 full turn on the adjuster nut, it is too tight!!! It will wear the cam lobes too much as the SBC engines are notorious for
I have had the best luck with 1/2 turn (no more than 3/4 turn).


There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.
