So my dad picked up a desktop dyno and ran my engine specs through it.

It seems real accurate based off how the car feels. It hits a wall right at 5000 rpms. My cam is technically good til 5800 and I was wondering why I wasn't pushing past 5000 very well. Dat low end torque though, 350ft/lbs at 1750 rpms does feel good. Peak torque is 402 @ 3500 and peak hp is 328 @ 5000. Probably getting about 275 to the wheels.
Heads are most likely the real chokepoint. A set of Edelbrock heads only picked 19hp on the desktop dyno though so it confirms what I already know: I'll need a new cam to go with any new heads to get the full benefit of it. If I go through with it, I'll being going more radical. I've settled on a XR280R-10 for now which will push my powerband to 2,500-6,500 rpm. The XR274 would probably be a better choice for the street and this block but the end goal would be to also build a 408 stroker shortblock and move everything over to that so the 280 seems like a solid choice.
Of course this is all in the distant future so long as I don't blow anything up. I am in the middle of my first job search in almost 4 years though and things are looking pretty good. Looking at cashing out over 2 weeks of PTO and getting a decent pay increase, so who knows? Tires and brakes first though.
