Cylinder Head Differences

Your intake will fit any series MEL head.

The early 58 was unique, and replaced by a head for 58/59 production. The 60/62 were 2V and slightly smaller ports. The 63/65 430 was a new style head for the 4V (requiring special pistons). The 66/68 462 head had slightly smaller runners.

I would try to port match with the gasket and head ports and not cut the intake as this thing will be gold with no modifications.
