Well, you say you have full exhaust, did you include full length headers? I think that would help a lot. Also, don't go with huge ports on your heads, assuming that you get them someday. I would also make sure you don't go too huge on the intake either. Trick flow makes some really nice ones with really huge tubes, but it's basically useless unless you have a supercharger to put some pressure through them. Also, you may want a stroker kit... That would really help torque matters probably moreso than horse. Just a few suggestions!
