Nice work and interesting results. The std ports are quite appalling so any gains should be fairly straight forward. I hear though the limiting factor with the RS head is actually on the exhaust side.

Update. Grinded some more to straighten ports out and didn't back fill. It lost flow as expected but i flowtested anyways; its just part of R&D.
I also used dykem to simulate fuel in the ports and chamber.

The low airspeeds that I highlighted are the cause for the little bit of fuel-wet-out that are left. I fixed massive fuel-wetout issues already as seen above with the pink dye.
