How do I adjust rocker arms on stock heads

stock heads you'll need the ford shim kit. only other way is if you have a stud mount head and have adjustable stud mount rockers.

The proper procedure is to be sure the pair you're working on have their lifters on the cam base circle (both valves closed). Rotate (clockwise) through exh. valve open/close, and then intake open/close. Once the intake is closed, they are both shut. Put the rockers on. Hand tighten til you reach zero lash - no gap on the valve stem end or the pushrod end. Then torque to 18-20 ft-lbs. while counting the number of turns it takes on the bolt. It should hit that torque between 1/4 and 1 turn. If it takes more than 1 turn, you'll need to shim that rocker up (.030" reduces about a 1/4 turn). If it takes less than 1/4 turn or if you can't reach zero lash, you'll need longer pushrods. If you kept them in order - put them back as they were - you should be fine just torquing them to 18-20 while the lifters are on the based circle.

I'm not certain what you mean....

I have no idea....
