Me too with CHE. VERY easy to install, no tools needed, fantastic machining tolerance. Several track days (HPDE) and just as quiet as when first installed. No wear measurements but nothing I can see or feel. Got mine direct from CHE.

A major design flaw, in my opinion, is how the inside edge of the bushings rub on the wider portion of the shaft if side loaded. To test this, assemble a rocker and rotate it back and forth on the shaft. You'll be left with millions of little pieces of brass because the shaft is not smooth where it touches the bushing and just grinds into it. Not good.
The brass bushings in my kit were badly oxidized and had to be cleaned really well. I could not see the oxidation on the bushings, but I could feel it when rotating a bushing on a dry shaft prior to assembly. Lots of green oxidation came off the bushings during cleaning. The rags turned green! After cleaning off the oxidation, they felt smoother.
Surface rust on the shafts. Required polishing to remove.
Poorly machined bushing IDs. About 90% of my bushings' IDs were stepped and not smooth. The fact that some looked perfect and others looked stepped was very unsettling. I sent that set back and was provided with another set that was exactly the same. I was assured that they were all "within spec". Scary. I simply don't understand why they all don't look the same. That points to QA/QC and machining issues.
Barely any bearing area, especially on the latest design with the oil groove.
I like the che as it has oil grooves to help with oiling. 700 miles no issues.

Older thread, new questions.
I ordered a Smith Bro's trunnion kit. The bushings are loose in the rockers. Rockers are @111K miles, from an L33/Suburban engine, that didn't appear to ever been apart.
Sent them back, and ordered a Straub kit....Exact same kit, even down to the location they were shipped from. [Piney Flat, Tn.]
New kit is loose, too. [Looks identical to the pic in post # 872.]
The previous kit from Straub, fit exactly as it should.
The questions: Is it common to find stock rockers w/ over sized bores? [The original needle brgs were tight, in these rockers.]
Is the CHE kit full floating?
