Exhaust manifold porting

Been going at it for a few hours with the die grinder. Porting it for a e316g, you guys think it looks decent enough?

Make sure they are double cut burrs, the single cuts don't work near as well. If you are looking for one locally, you can get one from Grainger for like $8 and it should last a lifetime.
