Who's rockers are these?

Only thick wall inductioned hardened rocker shafts live with needle bearing rockers.
I paid i think around 200.00 for mine from Dvorak machine. They out lived the first set of Ohio crankshaft rockers, no longer sold, the races wore and with a magnifying glass pick and light...I could move the inner needle cage and see the wear.
They were new to me then and I had checked them frequently of course cuz I didn't trust them ..like most people... but I know there was some power to had and probably be a lot more accurate than the other rockers I had which were like 1.45 maybe. I have another set brand new, red ones.. dunno if I'll get to using them, have comps and mp's bushed for over 7000
