I've heard it said, that aluminum rocker arms can leave minute traces in oil.
Anyone experience this.


And has anyone tried these yet?


Comp Cams Ultra Pro Magnum.

Like the previous generation, the new Ultra Pro Magnum™ Rocker Arms feature a fully rebuildable design. COMP Cams® will disassemble and inspect the rocker arm, replace the roller tip, axle, trunion and bearings to make your rockers like new. And with a nearly unbreakable investment cast 8650 chromemoly steel body, these new rockers are nearly indestructible! As further testament to the strength of this innovative design, we include a lifetime warranty against the breakage of the rocker arm body—for any reason. This may very well be the last rocker arm you’ll ever have to buy! The new COMP Cams® Ultra Pro Magnum™ Rocker Arms are available for most popular Chevy and Ford, street and race engine applications. Visit us online or call our toll free CAM HELP® service today to let our experienced valve train technicians help you pick the best rocker arm for your application.
 
if there is, its certainly not enough to worry about. arms like those are one of the most common upgrades to a sbc. not to mention liability for the manufacturer.

put this way, i wouldnt think twice about putting them in my engine.
 
Uhh, those are steel.


They have less weight at the vavle then regular steel rockers though. I've read that less weight than alluminums too.

I've got a set of Harland Sharp rockers on my 454 and a set on my 400. I haven't noticed any metal in the oil when draining. The 454 see all drag stip time and gets it's oil changed quite offten (about once a week when I take it out). The 400 gets changed about twice a year (maybe 2000 miles each time). A good filter should catch any/all metal.

I think if they are wearing, they are either worn out, or the geometry is incorrect.

Yeh, I know Dorian, I was considering these as well, they're chromemoly, and pretty new on the market, and supposed to be bombproof, as well as lighter at the valve than aluminum.
 
I took your first post to mean that you were wondering if anyone had tried those AL rockers. Sorry. :)

I've got the pro magnums, they have worked fine for a few years now, even surviving a broken rocker arm stud.
 
I was looking at those too, then these caught my eye.....dam what an addiction.
