Worth it to port/polish stock manifold?
Thinking about ATP GTRS Hardware with unitronics software, but also considering to port and polish the stock exhaust manifold. How much do you think it would cost?

at the very least you should gasket match it.
porting...may be not worth it. polishing, and gasket matching can be done at home for cheap.
i had mine extrude honed and then i gasket matched it myself. the extrude honing probably wasnt worth it.

port and polish is definetely worth it!! trust me i know.
I have been port and polishing for a little while now and you would be surprised with the gains that it gives. My buddy has been port and polishing for quite a few years now and we recently started a business. feel free to contact me if you have any questions.
As for the exhaust manifold, our stock manifolds are extremely restrictive. Each inlet has nearly a 1/4 inch lip. By gasket matching and smoothing out the casting lines, we have only had happy customers.
