Most trucks had the 8RT heads in 1952. The cars had the EAB heads. Mercury had EAC heads.

All 8BA/1BA blocks are pretty much the same with only a few exceptions. Trucks kept the hardened seats in the exhaust valve pockets but later cars didn't. After 1951, the rotator type valves were used so the valve seats would last better. The cam may have a casting number on it. There are a lot of little clues that will tell a story if you know what to look for. The 1BA block is identified by a casting number in the valve chamber. The crankshafts were bored larger at the flange end for use with automatic transmissions.

The truck and Mercury pans are rear sump. They should clear the radius rods but your 36 has unique front engine mounts so adapters may be needed to use the 8RT coolant pumps/mounts. The single belt accessories might fit better in a 36 too. The fan could be an issue since the 36 had the generator mounted set up. I know its been done but it seems like the 50/51 Mercury fan set up might be better but I don't know for sure. They use narrow dual belts but they don't stick as far forward as the 8RT fan set up.
