Need help identifying Big block roller rocker arm

I think those are DOVE rockers or something close to that name. IIRC they are now tits up or they ain’t making Chrysler stuff anymore.
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.
