Who's using the Comp Cams Retro-Fit Rocker Arm Trunion Kit
Im wanting to do this to my stock rockers before i blow needle bearings everywhere and am wondering what you think of them, do they help quiet down the valvetrain? How long did it take to install?
but for the 200-300 miles they did see i had no issues

I put 219k miles on my stock rockers w/o one failure.
When I built the LS1, I didn't want to use the ones from my 5.3L, so I bought a set of stock rockers with 30 - 40k miles on them and have ran them even harder than before for the past 63k miles...until recently.
I recently had valvetrain failure...several broken valve springs, a beat-down pushrod, a stuck lifter and a few w/ flat spots on the lifter rollers from beating up the cam lobes.
100k+ mile rockers still look great.
I read everything I could find about the Comp and Harland upgrades over the last week and I decided to purchase a brand new set of GM stock rockers for my current build / re-build.
I also bought new rocker arm bolts to replace the ones I now have 282k+ miles on.
The set was just a lil' over $140 shipped.
Just a lil' food for thought...
There are shops doing the Comp rebuilds for $199, using your old rockers, if you decide to go that route and don't feel comfortable doing it yourself.
I read a thread about the Harland Sharps being flawed as well somewhere along the line but that they were making them good if sent in to be rebuilt.
six o' one...half dozen of anutha'...

Ill be getting some for mine soon also. Does it matter if the rockers have 150k+ miles on them? Like the tips where the push rod hits and and where it contacts the valve spring? I'm sure those can get excessive wear right?
