That works on anything with enough area between the adjuster hole and the center shaft tunnel area.
Sometimes you get either more ratio, or more safety margin (or both) by reducing the adjuster thread size, but match the ball diameter to your original or you'll need new pushrods.
The new ratio has to be a substantial change to justify the work (not to mention using up the rockers!).
Example only: the distance from the shaft center to the pushrod adjuster ball center is 1-11/32" (1.34375"). and that from the shaft to the pad radius center is 2", the ratio is 2 ÷ 1.34375, or 1.488:1. Lift with a .280" lobe is .417"
Moving the adjuster 1/8" closer makes the ratio 2 ÷ 1.28125, or 1.64:1. This adds about .042" to the lift.
