I think he is probably referring to the Comp Cams magnum
rockers. These have only a roller tip.
Zak,
I personally have used the set up you describe in quite a few of my own
engines, & ones I've built for customers. The Comp cams roller tip
rockers are really well built and following their guidlines on the
appropriate pushrod is a must, unless their included in the kit. Using
the wrong pushrod can really cause problems. I repaired an engine where
pushrod length recommendations weren't followed by the builder and the
stock length pushrod actually shrouded the small oil hole in the rocker
arm. This deprived the rocker swivel ball of oil to the point that the
bowl of the rocker heated up til it was dark blue, seized and broke the
pushrod. That was on the good cylinder, another one seized in the open
position causing the valve to contact the piston........you know the
rest of the story.
If all this comes in a kit form, get the kit. As Tom Warner pointed
out, the Olds engine shares some unique rocker geometry with Chrysler,
Ford etc.
