1978 318 heads? Small port? Or large

This should be simple enough for some of you more versed in 318's than I. Some of you may have seen my other post about picking up a 78 dodge with a 318 and a 2 bbl. Was there a changeover year where all L.A. engines had the same 360 port heads? Despite 2bbl or 4? Or because this hog had a 2 barrel does it automatically have small port intake ports? Reason being im contemplating a 4 bbl intake, and want it port marched. But if its small port heads, im probably yanking it altogether as im not wasting the money on an edelbrock performer to put the planned efi (4150 flange) efi tb on.
Probably an ironic post as im not looking for power, just a cruiser, but I hate the uni-flange spread/square bore non performance intakes that sometimes even require the adapter plate.

1978

The 318/155 HP {4-Barrel} > did come through with the same Intake Manifold as
the 360.

Also, the 318/155 HP {4-Barrel} came through with 1.88" Intake and 1.60" Exhaust Valve Cylinder Heads.

The 318 {2-Barrel} was a small-port Cylinder Head only.
