FatNat,
I have a used set sitting on my workbench that belong to Len Freeman (AKA: LV GN). They are the jessel style rockers but I'm not sure if they'll work on "R" heads. I also believe that the early and late "R" heads take different rockers due to the relocation of the exhaust valve. One way or another Len isn't going to use them since he got a set of TA heads. Drop him a line and if they'll work for you I'm sure he'll give you a good deal.
