Rasp Burr Finish Experiment (Porting)

Those all look good. As long as the edges are sharp that’s what you want. I’d send it.

What you can do is port the manifold and finish with your papers rolls in 40 or 60 grit and go drive it for awhile. Make some passes on it. Then pull it off and burr finish it and do the same and see what you think.
A before and after comparison either on a dyno or drag strip would be a good thing. Breaking up those fuel droplets into smaller pieces has to help.
