Pretty good man. Looks like you are using cast flanges? The one to the turbo looks that way. Can't see what you used for a flange on the head. Welding cast has a few tricks for long life.
My only real gripe is grinding welds. Generally a fab/engineering no no. You loose a lot of strength at an already crack prone location.
Good work though
