While TFS heads are great heads, and I believe they can hang with a set of AFR 165's, but I don't see them outflowing a set of AFR 185's. I've seen both heads in person, and the AFR's look like better heads IMO.
Instead of having your heads ported I would just sell them and get a set of AFR 205's and a Victor Jr intake.
If you decide to stick with your heads, I would at least ditch the RPM in favor of a Vic Jr.
