I am currently building a 66 Shovel engine and dealing with some issues provided by previous engine builders and a few aftermarket parts.
While disassembling the rear rocker box I noticed brown sealant around the o-rings and screws of the rocker arms.
After disassembly of the front rocker cover there was no brown sealant and the front rocker shafts looked different in colour, compared to the rear shafts. On closer inspection, the machining was also different between the two sets of shafts, so I am assuming they came from different origins. I think the dark pair at the back of the picture are original.
The light grey shafts in the foreground of the above picture had the brown sealer on the O-rings and end screws.
