Today I started working on the valve train and I have some mixed feelings...after working with main studs and rod bolts from ARP it was kind of a brutal awakening to start working on these PRW roller rockers. The push rod adjusters feel like there is sand in the threads, and the adjuster itself feels loose in the threads. Yeah, I forgot to mention that one of the supplied studs is not straight, and will need a little massage before it can be used... Anybody having experience with these rockers? 7688607-P4302331.JPG (144 downloads) Last edited by Swedcharger67; 04/30/13 02:48 PM.

It seems there is no more than 5 threads holding the adjuster...see the pic attached. 7688613-P4302339.JPG (156 downloads) Martin, 67 Charger, 512 cui, E85, MegaSquirt MS3X sequential ignition & injection

Unfortunately nothing else about them was. Keep a VERY close watch on the roller tips. The axle/rollers on mine were sloppy loose in no time. Adjusters were junk too. I could go on and on but suffice to say by the time I corrected all the deficiencies, I had spent more than the price of a set of Comp Pro Magnums and then the rollers went FUBAR. Nice paper weights now. Kevin

For mocking them up I had found that the body of the rocker hung down a little farther than I wanted where the roller tip is , I had to grind a little away to keep it from hitting the valve tip. Other than that I also had to replace the adjusters. After about 1,000 miles the adjuster nuts started backing off. Happened about 3 times and then I replaced them. The only problem is finding the adjusters was a pain for me seeing I use ball/ball pushrods. Harland sharp was the only one who carried the correct ones. I think maybe 440 source had them also but I was scared of them being them same ones that came in the rockers. Other than that I have been happy with them. Also I am only running a 540/555 lift solid cam so I cant comment on how they would be with something with more spring tension.

With the 1.6 rockers my lift will be 527/547, Stealth heads. Ok, sounds like new adjusters might save the day. Thanks for the info!

Take care to have correct length pushrods so the oilrelief is correctly positioned. Careful shimming sideways to avoid the lips on the outside of the rollerwheel to hit the valvestem top. You could also grind the lips away, then they look more like the compcam type, but it is some more work. The rockers with the bronzebushings will be OK, the others without will gall on the shafts. Some work to do, but then they could be OK. Mine are 1,7:1. I prefer them, they should be more durable than the aluminum ones.

Turned out the first set weren't spotfaced so Brandon replaced them. The second set, the spotfacing wasn't 90 deg to the adjuster. More machine shop $$ and a set of Comp adjusters solved that. All for naught tho as the roller tips were junk too. Kevin

I spot faced the top of the rocker next the the lock nut by hand, no help. Went back to the male style adjuster and pushrod had no further problems. Doug
