That just goes to show where the most important area to improve is, ie the short side radius. Hog as much as you can off this side and you will get even better flow, only limitation is running into something, like a valve seat or in some cases water jackets (not a problem common with Porsches). Just a smigen of a sharp edge on this surface can hurt flow by as much as 40%!!!!!

By the way that is one BEAUTIFUL finish in those ports.
