Please tell me what would make the #5 plug gap close up all the way?

If there is NO damage or signs of damage or impact, it was done prior to installing I would say..
A plain ole 350, the plug don't look damaged. A piece of carbon could have done that, but it would be rare. You can run a compression test on that cylinder, then on another one and see if they are close.

Put a set of AC R45TS's in check the gap on all of them b4 U put them in and see what happens, like said already probably installed that way, it wouldn't be the first time a "Brand New" plug got dropped @ some point bending the ground electrode, or on the cheap side re-gap this plug
