Hahaha! Yeah, turns out that this motor is like an orphanage for forgotten bastard rocker arms! They were scrounged up from 3 different sources (all members of the forum I believe) over time. Yes, the left and right intakes are different and the exhaust rockers are also a different generation/brand/style. And aside from the 4 left intakes that appear to be NOS, the valve pads on the rest were pretty roached and Mike did a phenomenal job of renewing the radius on them.
You really made a silk purse out of a sow’s ear Mike!
