Default L98 Power Loss

I have a brand new engine. Everything was running reall really good until.... I drove it hard for a about 4-5 pulls through the gears and then now feels like i have a honda engine. The car does not want to idle and passenger side header is getting hot instally on start up. The car still fires up rite away but is really rough. I did compression check on all cylinders and got 150psi on all, checked rocker arms and pushrods, changed ignition module and cap and rotor, checked timing. Cannot find the problem. Has anyone else experienced this? The only things i could think it would be is:

Cloogged cat?
Bad injectors?
Fuel Pressure regulator?
Computer problem?

The car has:
Dart Pro 1 Alum heads
Hooker headers
TPiS Torque secrets cam
New pistons and bearings .030 over
Had the injectors cleaned by TPiS
Custom computer programming for the supporting mods

If one side gets hot fast, I would think there is an injector problem. Contact JICInjectors and toss your rebuilt injectors.

usually hot exhaust means lean condition, could be injectors as stated above

Indeed you might check the fuse on the right bank of injectors; if ok, use a trouble light to see if they are firing.

I want to thank all of you who replied to this thread and for pointing me in the right direction. It turns out it was a fuel related problem and 65Z01 hit it on the head it was just the injector fuse. I didnt even know these years had a fuse for that but thanks again to everyone.
