FWIW....... this one and an actual Comp Pro-magnum fit just fine.

The rocker that had the contact with the retainer was a PRW, which I’m told is the same as the SM rockers....... but I haven’t had a SM rocker in my hand, so I can’t say for sure.

I dont doubt you'll find some rockers that will fit. I doubt the geometry is correct.

And that's the issue. No matter where you out the stands or how or low you make the saddle, every single rocker arm is different so it makes just bolting a rocker on and hoping for the best is a crap shoot.

I do know that the Mancini rockers will go on the TF heads and be very close. So any other rocker probably won't be.
