360 magnumblock?

Actually the rockers are more like Ford. They are pedestal mounted verse the stud mounting of a Chevy. The pedestal mounting is much more stable at high rpm than a stud mounted rocker.

Lots of folks retro fit Chevy small block roller rockers to magnum heads but the stock stuff is perfectly good up to 6000 rpm.

I'm not sure what you mean by, "more like a ford". The Magnum 3.9, 5.2, 5.9 all use a stud mounted rocker as opposed to the LA shaft mounted rockers.
My point being, I prefer the single shaft with five studs to individual mounted rockers...each on their own stud.

This article details upgrading the Magnum rockers:

These are the typical upgrade for the old style shaft mounted rockers:

Granted, these are for a big block....but you get the idea.

P.S. I would stay away from any of the cheap ebay rockers that have needle bearings inside them to ride on the shaft.
I have also personally had way too many problems with Comp Cams roller rockers.
I would stick with either Crane or T&D
