1988 5.2 which intake port size?

I had an 89 factory TBI engine that I converted to carb in my Duster about 15 years ago. It had the 4323302 cylinder heads which have the small ports. This won't be a magnum engine.

The large port are the 318 police engines with the 4 barrel carb. As far as i know, no other version of the 318 had the large ports.
