Default Re: Adjusting valves

The lifters should have flats on them for a wrench to keep them from turning. You may have to grind down a wrench to make it thinner. You will have to measure the clearance when the cam is at the heal and then turn the cam so that it is at the toe to lift the lifter. It is a trial and error procedure.

You do not have to take the head off.

The Model A engine does not need the valves adjusted very often.

Lots of engines have the tops of the guides for the lifters machined lower so that the flats on the lifters are accessible when the cam is at the heal.
