Thoughts about what happened?

Just finished a rebuild that combined a 1973 head #2440 to a later engine block 3836 to get the newer rear main seal. After a short break in period the exhaust cam bearing on #1 froze up and melted the seal. Upon inspection it looks dry compared to the other bearings. I had to use the newer sump and oil pick up with the newer block but I am wondering if the old head was not compatible. Cant tell if the belt jumped but I think it did as one of the rubber teeth is chewed up. Oil pressure at start up was a constant 60 lbs and the engine maintained normal temp the whole time. Thoughts about what happened?
