CHE rockers are an engineered solution that is race proven without the issues associated with stock or the HS repalcement needle bearings.
This rocker conversion definitely ends the needle bearing issues, once and for all.
$ 420 Exchange + shipping
$ 640 Outright - (new GM rockers) + shipping
Please call and speak with me or Keith

Since the rocker bearings are not pressure fed, is it wise to use a bushing type bearing with the modern oils we use? NASCAR racers that use these rockers use motor oils with a high zinc content. I'm not flaming, just curious.

Last, if synthetic oil was so bas for needles in the rockers, as told to me by HS, why does it work so well with roller lifters?
Bottom line - no worries with bushings and synthetic oils...

this is IMHO and some info for the people interested.
i spoke with Ed from CHE yesterday and we had a good conversation about the good and bad options; valvetrain in general and the success they've had with application. i was sold, mine will be sent out next week.
he said they have many sets out there in high HP LS7's running up to 8200rpm with zero failures to date. he was very professional and seemed to have alot of experience in the field.
not that this adds much from the technical standpoint, but i've been researching an alternative for a while and i see no reason to look further.

"Last, if synthetic oil was so bas for needles in the rockers, as told to me by HS, why does it work so well with roller lifters?"
Quite possibly because the roller lifters had the benefit of break-in with zinc??? Or maybe the rollers in the lifters were turning on a surface with greater than Rockwell56 hardness???
Regardless, am I the only one who thinks taking roller bearings out of a high reving engine and replacing them with bushings is a step backwards??? I know the crank/rods and cam are running on what are effectively bushings, but they have an oiling system specifically design to accommodate that, can the same be said about the rockers?
Then there's the Yella Terra option, full roller bolt-on, (assuming they get their rocker cover clearance issue settled) for $379.99 a set outright...vs $640, it looks too good to be true, I guess time will tell.
Cheers, Paul.

What I am saying is this - the factory rocker uses a needle bearing supported trunnion and is notorious for spilling the needles out themselves and into the engine. I can only speculate as to why this occurs but it's pretty obvious that it's either cost or design related.
If you use the factory rockers the CHE bushing is by far the superior upgrade in this application.

Charlie,
For installation, can you just torque these down to 22 Ft/lbs and be done with them? Or do you recommend following the procedure in the service manual (rotate the engine to TDC, install half of them, them rotate another 360 to install the rest)

So then, it's fair to say CHE is by far the superior upgrade if you plan on using the factory rockers since it now seems as though it isn't just the 'factory' who hasn't figured out how to stop NSS (ie. needle spitting syndrome).

So what are the disadvantages of these?

$$$$$$ , but it beats pulling your heads to have them machined to accept Crowler or shaft mount system.
The price point is right in betwqeen the H/S option and most shaft mount systems, plus its an easy swap....unless you have those damn Katech Valve covers and have the vents plumed like mine.
thanks again Charlie! If someone could get you out from under a car or off the dyno and into the board/marketing room I think you would be quite busy over there.
