Page 1 of the Chrysler Hemi;
All Chrysler hemis (both low deck and tall deck) used basically the same valley pan and can use the same intake manifold. The 331's and early 354's used an intake that had a thermostat housing and water crossover passage, the late 354's and the 392's didn't have this. Instead, the later engines had a crossover/thermostat housing that bolted to the front of the heads. Either style of intake will bolt up to any low or tall deck engine. The intake ports were changed on the 392 heads to allow this, and sit lower on the head. 331/354 heads can be used on a 392 if 3/8th. inch adapter plates are used.
