Now it's my turn to motivate you with a little pressure Jerry
I worked a little bit more around the guide into the bowl. It's still not ideal, but there are no ridges present where the bowl transitions past the guide anymore. I finished up by "gasket" matching the exhaust port and making it round(er). I left a couple MM of a lip inside the gasket to ensure adequate clearance for any gasket "squish" that may happen. I then blended it in with a taper back into the rest of the port. I still want to do a little finish work on the texture of the port to smooth it out some more, but that is more my OCD than a necessity.
