Need help identifying Big block roller rocker arm

Thank you sir, I appreciate the info.
I’ll try to research dove and see what I can find.
Were they any good, from what you recall?
Basically if you were comparing would you say:
1= speed master/procomp.
2=prw/440 source/pick your middle tier
3= Hughes/td/Harland sharpe.

Im guessing one of the first two categories.

Thanks again For your time.

IMO they are every bit as good as the Crane rocker, which I think they copied. I’m not a fan of needle bearings on a reciprocating shaft. I’d rather run plain aluminum until they get some wear and then have them bushed. Or, bush them when they are new.
