Well ive got a deal cooking on a like new set of cat 1.6 rockers for a C note. I thought with my 325psi spring pressure and tight side Clearance for oil control...? I will change the adjusters to smith bros. I think ive seen guys have success with these with flat tappet cams

Mine have worked out fine so far. They have the same bearing as the Harland's (at least mine do). With that said I think it helps to pay attention to the shaft size. Harland uses an .875 shaft and when I found the specs on the bearing it is made for an .875 shaft. I run mine with Smith Bro adjusters and a hardened .875 shaft made from Thompson rod.
The ratio is off but at least they are consistent (1.7>1.655). They were also spot on for valve tip placement on my 906 heads.
I had a store credit with KMJ and took the money and bought some of the non bearing aluminum rockers and I have to say they do not look bad at all. I would still change out the adjusters. When I mocked them up they will require shorter pushrods, which they told me was some feed back they got on some of the sets they have sold. I bought them as I have in my mind at some point I may try the Comp .650 cam and with my 1.65 rockers my p2v clearance isn't going to happen.

You can buy Thompson rod in an .875 od within an 1/8" of the correct length, which works fine. From there you just have to have them drilled (center, holddowns and oil). I tapped the ends and screwed in plugs. The Thompson rod was less than $50 to my door and less than $50 to have them drilled.
