Sounds like you are running dangerously lean.
Check fuel pressure and then get the injectors tested.

Or your timing could be off. Usually, the manifolds/headers get hotter or glow red when the timing is retarted. This causes the air/fuel mixture to still be burning while in the exhaust phase of the cycle. So, check your timing.

could also be a clogged catalytic converter

disconnect the exhaust at the crrossover and let us know what happens
