ESR Porting looks ruff, however; ruff is not necessarily bad as long as it is not too ruff…

Wes350x looks better; I would say it is acceptable. Porting does not need to be polished; a bead blast finish is actually better as long as all the ruff high spots are properly blended. A balanced flow across all port windows, including exhaust, transfers and boost is the sign of a good port job. Porting and testing on a flow bench is the best way to go, however; cost will be in the $450 range as time is the dollar factor. I have seen good porting take 8 hours or more including flow bench work.

Neil sounds like an excellent choice; BDT Motorsports is an excellent source as well. As stated correctly by 1promodfan; don’t expect a +$300 port job in a $600 cylinder, you get what you pay for.
