You're making decent torque due to the displacement increase and long tubes. Other than that, the cam you chose is fairly mild, and the stock heads IMO are corking you up enough which is most likely why your hp number is somewhat low. Get those heads ported to support the rest of the engine and I think you'll see a sizeable gain.

The potential is definitely there with just stock heads, just depends on how much you want to spend on the porting. Quite a few people use http://www.elliottsportworks.com/ with good results. 400+ hp to the wheels with ported stock heads N/A has been accomplished many times.
