(SOLVED) Dead cylinder at idle? Low temp on header collector

That's about what my #1 temp is too. It's been a year since I hit mine with a heat gun. Just got the engine back in and going to plug the pcv valve and try breathers. My intake valves are all sludged up, just looked at them with a borescope . Trying to figure out why. I can let you you know what my temps are when I start it. The center cyls are the hottest. You may not have a problem. Leak down test is best.
