Hp/tq estimate on 5.9 magnum?

This will be a everyday driver. Just curious on what numbers to expect from this simple build from parts I had in the shop.
Stock rebuilt 5.9 short block
stock pistons
stock rods&crank
Mopar .028 head gaskets
new magnum heads with bowl blend short turn radius and slight runner clean up
lunati BM2 280/480 cam
RPM Air Gap intake
Holley 750 vs carb
headers
Pertronics flame thrower 3 billet distributor
This will be in a 3200 lb Dakota . Just curious on how much up and tq to expect from this.
Magazine articles say stock 5.9 mag engine with just air Gap and carb makes 300 hp with stock cam. This is not my cam of choice, but I had it already and im going to use it. Will be using 1.6 rockers so lift will be higher . Im guessing it will make 325 hp and 350 tq. What do ya'll think?
