Moved from All Questions thread.

Just finished my head gaskets and the truck is running much better than before, smoother idle, no more hesitation, and no more white smoke. but I'm having some overheating issues. Doesn't overheat idling, only while driving. If I stop at a light or stop sign and raise revs in neutral the temp will go down a bit.

There's a new oem water pump, timing belt, thermostat and fan clutch.

I've burped the system using a no spill funnel while parked on a hill.

The only thing left I can think of is clogged coolant passage or I seriously fked something up doing the head gasket. But the car feels like it's running better than ever except for the overheating issue

What else could I be missing?? Would having the tstat jiggle valve in the wrong orientation cause this much of an issue?

I havent pressure test the cooling system or compression check yet, I guess that's next up.
