Ray, The valves have a different stem diameter and are sodium filled, but there are modern substitutes. Sometimes the accessory bracket mounting holes are not drilled and tapped for the power steering pump and generator. The cam, distributor, front cover, oil pan, water pump housing, oil pick up, oil filter base, and intake manifold will have to be changed. A lot of trucks used front motor mounts, so make sure they are also cast on the sides of the block. However, the exhaust manifolds with the 4 bolt flange are great for improving any 331/354/392 Hemi and are sought after.
