Bill wouldn't be able to tune your 3.4 anyway. You'll have to ask on FTv6 to be sure, but I think PCM4Less does 3.4 tuning.

Getting some work done on those heads and your intake manifold will really help out that motor, they are notoriously restrictive on the 3.4 cars.

The other thing you might want to think about is a Gen III top end swap (using the heads and upper and lower intake from a 94+ FWD 3100 or 3400 v6). These heads and intake flow waaaaay better than yours, but they do require some custom work to make them fit. I know at least one 3.4 guy on FTv6 has done the swap.
