JDM Type R B18c w/ 94 GSR Head

I've heard in various places that there is some benefit to running a GSR head on a B18c5 block (or a JDM B18c whatever you wanna call it). I'm currently waiting for my JDM B18C block out of a Type R to show up. It's going to be replacing my torn up 94 GSR engine. I was just wondering if there is some benefit that could be gained from using my GSR head with all the type r internals on the Type R block. If so what sort of gain could I expect.

again i'm not too sure but i think the b18c5 head is more flowing than a gs-r because it comes w/ a mild port&polish right? i wouldn't see why a gsr head would benefit, but maybe i've been misinformed, but that's what i think.
