Cold exhaust, hot valve cover.

If this is my problem would this mean the passenger side isnt getting enough air or is getting too much?

My exhaust flow feels the same on both sides, it's just the temperature that's different. However I guess the engine is gonna push the same amount of air regardless of what kind of combustion is happening. Does this sound accurate?

I assume this is all being checked at idle, or close to it?
Maybe it straightens up at running speeds.
