I have been running Jegs Aluminum roller rockers on the last few engines. I believe they are made by lunati 
They went four seasons in my car shiting at 7,000-7,200 no problems.
I was replacing my pro mags every year due to wiped out trunions

Scorpions... Used on the last dozen or so LT1 buildups I have done... Zero problems on any... These are all using the full-bodied Scorpion rockers...
The biggest issue with the Scorpions is the valve cover clearence in regards to strengthening ribs internally. On most of the aftermarket aluminum covers you need to grind down the ribs to help them clear the rockers. It is the same issue with stock LT1 covers, as the internal ribs get in the way. LT1/LT4 Corvette composite valve covers do not have this problem as they have no internal ribs, but some of the LT1 composite covers have internal drip rails that to be ground down to clear.
Narrow-body rockers will clear just about any valve covers.

Are the endurance series larger than the race series? Mine cleared stock style valve covers with just the removal of the inside bracing/webbing. I have had good luck with Scorpions and will continue using them. Conveniently they are local to me 
The newer Comp Cams Gold rockers are just rebadged Scorpion Race series.
Again, I don't think there is any issue with the SBC rockers. Just the LS-series, and even those were a while back. Since then they have fixed the issue.
