Can’t get Harland sharp rockers to fit on head?

Another thing you need to look at is the adjusters. When you adjust the valves, the adjuster should have 1 or 2 threads showing on the underside of the rocker. Much more or less than that and you will need new pushrods.

The amount of adjuster protrusion is 9/32 (~.287) and that includes the ball. Depending on the ball that is usually 0-1 thread showing.
