The "B" motor (361, 383, 400) has one pan, and the "RB" motor (413, 426 W, 440 & that oddball RB383 back in the late 50s/early 60s) has one pan, they are not the same. That valley pan is also the intake gasket and its a one time use item. If its not replaced, they tend to suck oil up between the valley and the bottom of the intake ports.

Are the Intake Valley Pan Heat Shield the same for the 383/400/440? I know 440's valley pan is a little wider as are the valley pan hold downs, but is the heat shield used the same or is the 440 one wider as well? Think about that, I have never seen both of them beside each other but I would bet money they are not identical Parts book shows different part numbers for the end rail reinforcements between the B and RB so the shield would have to be different also. Can't find a number for the shield itself.

The heat shields are the same for the 383/440 that hold the insulation
Silencer Package Was Called Part number - 1879 747 383 - 440
The holes are spaced 100 % the same on the hold down bars for 383 / 440
On a 440 the valley pan hold down bars are just longer on the ends , hence different part numbers for bars
Picture is 440 RB Hold Down Bars - Heat shields for 383/440
440 & 383 both have the same holes but the 440 is 8 1/4 long & the 383 is 7 1/4 long
