Good quality 1.5 roller rockers?

Maybe I can stay with these factory units if I get it sorted. Gary at Rocker Arms Unlimited says they should have caught any wear in the threads so is sending me a couple more bushed and prepped arms.

Also I have a good local Mopar machine shop so I'll check with them to see if I could have these tapped for larger diameter adjusters?? I know that RAU can do this, but I do not have time before my summer events.
