That much heat is usually caused by overly lean, caused by too much air or not enough fuel, or a combination of the two.
I already bought 6 new injectors, so covered not enough fuel. Making sure the intake seals should cover too much air. Think that should keep the new motor from suffering the same fate, any thoughts?

This isn't entirely accurate. Lean burns do not cause excess heat. Lean burns can cause detonation, which forces the flame wave in unitended directions and consequently cause certain areas to run hot. Lean burning by itself, however, runs cool. If you don't believe me, grab a blow torch and max out the flame. Then start turning down the fuel knob and see what happens. A more objective proof of this lies in aerospace applications, where pilots have relied for many decades on cht and egt readings to monitor their engine status. Any pilot who understands these number will back up what I am saying here.
