I could be wrong, but I am 99% sure they all run the med riser port despite being "usable" on a low riser. Interesting reference though, any details on port size from your source?

I have never seen any Edelbrock head with anything other than the med riser port, and each of the part numbers above shows the same 170 cc intake port volume, so hard to believe any one of those have the taller early port without changing volume

(unfortunately they dont show intake port dimensions on Summit, thats where I looked for a quick reference)

The intake will still work fine, just a little port mismatch, thats all
