I adjust my valves with the engine off .................... pull the distributor cap and watch the rotor to get an idea of which cylinder is at top dead center on compression stroke..
This is ABSOLUTELY NOT the way to adjust valves except maybe a bone stock cam. If you have a hot cam, the lifters won't be on the "heel" of the cam at TDC
The best way to adjust valves with engine off is to learn the "EOIC"
This means that you bump the engine on a given cylinder until
The EXHAUST valve just starts to OPEN, then you adjust the intake valve on that cylinder
To adjust the exhaust valves, you bump until
The INTAKE valve is almost CLOSED and adjust the exhaust valve on that cylinder
