New 91 GT 5.0 motor with 97 explorer intake and plenum, headers get red hot and valve covers real hot to the touch in less then a min idle, timing set, vacuum good, not sure if I'm missing a step, have the factoryTB, and egr plugs in back of heads, EGR still on TB, coolant line from TB to intake has no spot to go, not sure if that's my problem or not?
