HELP!!!273 rocker shaft and rocker install

This may help...




That chart works great on V8's

I use what is known as the "EOIC" method, which works on everything from Briggs & Stratton to turbo compound Prattt & Whitney radial engines.

What you do is, turn/ bump the engine until............

The EXHAUST just starts to OPEN, and you set the intake on that cylinder.

You turn the engine until....................

the INTAKE opens, then going closed and "nearly" CLOSED, and adjust the exhaust on that cylinder.

You can go in firing order, or start at the front of one head and go to the rear, which is what I usually do.

What do you have for heads? Aluminum vs Iron heads affect cold/ hot adjustment
