Another Update:
Got the new camera Friday and tinkering with it this afternoon. Much better image quality than the other one I had. Only issue is it's focus distance made it hard to get a good clear image of the valves.
Video of the valves closed - trying to see if they were seated properly - if you're curious:

(Didn't see any signs of a bent or burnt valve, just covered in gunk- though I'm certainly no expert)
