The location of the pushrod seat directly effects the effective length of the pushrod. Now, a rocker arm is NOT constant ratio. The ratio of a rocker arm changes constantly as the ends rotate around the fulcrum. Raising or lowering the pushrod seat raises or lowers the pushrod, changing the effective ratio of the rocker at various points.
