Did you check the for sale section? Or the wanted section? Seems you're beating a dead horse in here.

I think you'll probably have to port them yourself. Not that they're not out there, but there just can't be many. Most don't port the bottom end or the middle. There are a few sets of cast runners on the boards and on Ebay though. ...I wish you the best of luck with the runners and the whole engine!

I already have a FULLY WORKED INTAKE.
Siamessed ported and polished plenum (gasket match at 1.75")
Ported polished SLPs 1.75"
ported and polished -stock- base (gasket match, 1205, 1.75"?)
I call it the "MAXPORT", I shift it at 5500 (for now...) as the rpms go up I can see (even on narrowband, wideband needs a new sensor) the afr goes lean. Short shifting causes an e.t. AND mph loss
I havn't put my afpr on yet-

That AFPR will lean or richen the mixture at all RPM. So, by cranking the FP, you'll fix your high RPM lean condition, but make the low RPM overly rich, when it is/was correct.
Fully siamesed runner and partial/fully siamese base will make this condition even worse. The more you change the intake from the factory flow, the more necessary tuning becomes.

Have you tuned it yet?
I'm planning to install a fully ported base under the runner/plenum set up that I posted earlier, and to swap on a set of RHS heads in the next few weeks. I'm planning to datalog with the stock tune and my current tune, just to really see where I'm at and how well it runs. Figure that'll be a good starting point for a new tune.

Stock tune. It doesn't "loose" mph and e.t from short shifting. Letting the trans shift itself at 4500 makes the car run nearly the same e.t. and mph that it ran wit the stock intake.
