Wondering if any porting gurus could share their thoughts on how this porting looks, just picked up this car/motor the guy stated it was done by Magnus.. true or false? Will be getting the exhaust manifold off tomorrow also

I can’t tell you if magnus did that job, but from what Iv always been told you don’t really want to make the runner section bigger. Smoothing out the valve area is more important. But that’s just what my local machine shop said when they ported my 6 bolt head, and used a flow bench to test it. If i was you I’d take it to a machine shop and see how it flows. This is a picture of what my head looked like after the machine shop ported it. As you can see they left the runners basically stock, but hit the valve area near the guides pretty heavy.
