They both have the same size Inlet and Exhaust Valves.
The Exhaust ports from memory look the same as with both of them; however the inlet is more oval in the Mivec head then the GSR.
As for flow, from previous research the Mivec head does flow a little better then the GSR, however in my opinion getting the Mivec head's main gain is from the bigger cams (obviously) however if you got a big set of cams for the GSR head I think it would probably make the same power / flow the same amount, the only difference is the one with the Mivec head will idle nice like stock, but the GSR head with cams wont.

Another thing to think about if you dont mind a lumpy idle is the Mivec head is heavier and has more moving parts which can lead to more headachs if it decideds to not work the way it should. (Which modified cars never do)
