Im running older versions of the Comp Cams brand (red anodized) 1.6 roller rockers, studs, guide plates and oil-thru pushrods. All top quality parts, not sure about the negative opinions, maybe it’s just Chevy engineered parts on a Mopar, and the question asked on a Mopar site= Negatives....but elsewhere likely different. I’d forget the notion of always shopping for cheap prices, cheap is cheap, think of it as another “you get what you pay for” scenario. You got three options on Magnum style: oem, Mopar Performance, or a setup by any number of brands such as what I run. There’s well known quality: Crane, Lunati, Scorpion, Comp, Howard's. That’s it. Odd name no name pro-form or don’t even......
