Questions

When you make the call, ask about oiling the rocker via the pushrod. lA rockers are not normally oil this way and the rocker must be able to be pushrod oil feed by design.

PRW & Comp are the only two rockers I know of off hand that allow pushrod oiling. I’m sure there’s others. You will need a new pushrod due to the OEM Magnum pushrod not being the correct length.
