What hp and torque am I making?

I just got done rebuilding my 360 and just broke it in on a home built engine stand. I put all new bearings in the engine is bored .03 over. It is a low compression smog engine. So stock crank and slugs were put back in. Added double roller timing chain, comp cams 268xe cam, Chinese knockoff rpm airgap intake, 650 double pumper brawler carb, and Doug's headers. It does still have the smog heads with the factory springs for now since I was just breaking in the cam. Will change springs later. Has a proform disty with a flamethrower coil. So as it sits right now what would the power numbers be? And if I decide to get aftermarket heads. How much power would I gain on a low compression engine?

Thanks in advance for responses.
Also this engine is going to be paired with the new tkx tremic perfect fit kit from sst.
So I'm excited to get this combo in the duster. Coming from a little slant 6 and 904 auto.
