Can anybody ID this port job?

[Muggzy]

This port looks like it's had some work done but I think it was just some "clean up" I'm no expert in porting so is there anyone out there who can tell me how much porting was done to this cylinder? I realize this is just the intake side and I have not taken the exhaust fitting off the other side yet so I don't have pics of that side. Just looking for some sense of what's been done to this engine.

Thanks

Very little has been done,if anything just a minor cleanup.I would say that no builder did that,if it went to them you would get the real deal.IMO
