Default HP guesses?

All right, finally have a combination and I have everything. Just got to get it together. I have a stock 98 Evo with professionally ported heads with stock valves. Powerhouse 500 P cam ,screaming eagle 10-2:1 pistons,HSR 42, Ultima single fire ignition and super trap two into one exhaust. What y’all think?

It was ~20 years ago, using a Crane 316-2 cam, IIRC, it went 91 TQ and 95 HP. Stupid fun in an FXR
