Who's rockers are these?

I bought those T&Ds plus the pushrods off a Chevy guy and quickly found they were gonzo overkill for my build so I flipped them. He got them in a storage locker buy and didnt know what they were for so he posted it up on his chevy forum that I was somehow browsing at the right time (I don't even own a chevy!) . He sold them for about 10-15 cents on the dollar so I snapped them up without any questions. They had some serious ratios on the exhaust. Ever see a SBM with a 1.75 rocker? I had to replace 3 of the bearings but they were available and just pressed right in with a few washers and a jackscrew setup.
