What brand rockers are these?

Summit will sell you a single blue proform small block roller rocker for $25. But it is a 1.5 ratio, and not offset like those shown.

The Indy bb rockers are shaped completely different

Those Rockers look like a blue version of the black Indy 1.5 rockers that came with my Indy Brock SBM heads( or now call the Indy T/A head), and they are big block rockers. I was told at the time by Indy they would work good with the roller springs I put on them( 225# on the seat and 600# over the nose), they were wrong. Half way through the second season the rockers started splitting behind the roller tip on the part that wraps around the shaft. I put a set of Hughes big block rockers on in 2011 and those are not showing any signs of cracks or failure to this day.
 
The pic with the offset rockers......
Those are Indy -1 SB heads.
Those heads use BB 440-1 rockers.
The ex rockers are the same as what the OP has on all 16.

The post above about the T/A heads...... those heads have the rocker stands machined farther from the valves, and as said use std BB rockers.
That combo of parts are more than likely what the OP has.

The rockers themselves are std BB rockers....... with shafts and hardware to use them on their T/A heads.
I’ll be surprised if they aren’t obviously too long on the SM heads.
