Stopped up cat can cause this. Did you do anything with the timing of the engine? If so timing issues might also cause to high of exhaust temps. But if you still running the factory cat I would just about bet it's stopped up. Is cat glowing red or another part of the exhaust.

Manifold glowing red? Are you sure you put the plug wires back on correctly? Did you just replace the ignition module or did you completely pull the dist out?

is the engine temp ok (195-205)? thermostat might make it run rich and eventually collapse cat.
