RyanJ - I have a couple of sets of econos and race heads(w2-long valve) that I have had for 20+ years
I have alot more port work on the econos then the race
Bought mopar roller rockers (blue) shafts, &(alum)stands about 20 years ago
After milling pedistals down and moving hole back in shafts roller is still way of center of valve tip.
I know the rockers will need clearencing for the springs and still have to clearence for push rods.
Could I call you and pick your brain a bit?
