#2 cylinder not burning hot?????

Tested resistance on wires, swapped wires on good cylinder to the bad cylinder, no change.... Not a wire

pulled pushrods, measured and micro'd. All within specs. No damage

pulled lifter and measured intake and exhaust valve moving measurements. All within specs

changed plugs with another cylinder and made no difference. Good cylinders were still good and #2 still dead

changed cap with properly running 73 satellite including all the ignition system and made no difference

thanks for the suggestions, this is going to be an issue that someone comes across and says "ah haaaaaa", i remember mine did that once. I cannot figure this thing out. Intake may have crack or warpage. Thats my next step
