How to tell Zenki/Kouki SR20 differences?

How do you tell if you have a zenki or kouki sr20? I tried searching but didn't come up with anything on how to tell.

IIRC the front of the engine will be ribbed like a heat sink if it's a kouki and if it's zenk it won't have that. someone can correct me if i'm wrong.

I matched up the part numbers for my ECU and MAF, and I have a Zenki S14 SR20DET. Hopefully that might help.

Usually doesn't matter, but... Zenki will be a 2 row ecu plug and the Kouki will be a 3 row connector.
