What is the difference in the right and left intake valve to the middle intake valve? What would happen if there are put in wrong? Thinking this could be the issue.

The middle intake valve is considerably longer than the other two. If they got installed wrong it'd be impossible to get the valve clearance set right.

Shorter.  And not by a lot, visually.  it's only obvious side by side.
