What brand rockers are these?

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.
