So the body of the rocker around the roller tip is larger than the diameter of the roller? Pics would help. Maybe your issues are fixable in another manner. J.Rob

Maybe you need the cut down valve locks if you've got rockers hitting them...
Or replace the valve locks to a type that don't stick up like that, sounds like he has valve locks for use with lash caps?
I'd replace the CCJ rockers personally ...

Those look different than my CAT rockers? Looks like nicer adjusters too.

Mine where sold as PRW rockers,but when i got them they had a faint cat symbol on the bottom.I bought them 3 or more years ago so may be the newer ones have changed some.I see yours are way down from the roller.I wonder if it has something to do with them being 1.7 verses my 1.5s.Mine are almost level with the roller but there was a few that would touch the valve so i ground them.

Pic of pushrod cup oil holes. With the supplied adjusters the upper adjustment would be with the adjuster flush with the lower part of the rocker arm body. It look like you may only have 2-Turns (maybe 3 max?) of adjustment down from there, So correct length pushrods are required. The stainless bodies are bushed, and the roller does not seem loose.
I run ProComp rockers that had these same adjuster studs in them when I got them. after breaking a second one of them because of this limited adjustability, I called ProComp and talked to them about the issue. They agreed that this design was flawed, and had changed the design of this component. They were happy to send me (16) new studs, that were of a much better design.
