I need help
I have 79 F250 4x4 with what i thought was a 400m in it, I recently started to swap the 2 barrel manifold and carb for a 4 barrell, when i set the manifold in i noticed that the 2 center ports on the intake side of the heads are exposed. according to the part# on the manifold it's correct for the 351/400m, and the decal on the valve cover lists it as a 400 i'm thinking someone swapped heads at some point. How can i tell what the cylinder heads are?
