So once I pull the camshaft position sensor how would I be able to tell if they're aligned properly or not?
1. The two slots, one each camshaft should be horizontal (3:00 to 9:00).
2. The slots are off center. Intake should be above center and exhaust below center.

Else, you could install the camshaft alignment tool on the rear end, then get the three marks on the front aligned.

So they're not those two things in the first picture are they? When I googled camshaft position sensor it showed just the black thing in the second picture that comes out with a single 10mm bolt... Then I noticed the big black circle that the sensor goes into, and I'm wondering if that's what I'm supposed to remove? The whole black circle thing?

Sorry it put the pictures in backwards. So when I said the two things in the first picture I'm talking about the second picture now, the bottom one..

Sorry I realize I need to take those 10mm bolts off to see the slots... I'll let you know how it looks after I do

Ok here are how the slots look. I'm pretty sure they are exactly how you were saying they should be.

I used my impact gun on 100psi and it still turned the cams slightly counter clockwise as you can see... I'm pretty sure I could eyeball those back to where they should be right? Kinda makes me nervous though, I was worried this would happen when I took out those 10mm bolts, I'm sure it's a common mistake though right?! I hope there's an easy solution lol

Look like they are both a little off. (Assuming the front three marks are aligned)

You could use a straight edge. Use the seam to align the straight edge.

Hard part will be keeping the cams in place as you tighten the hub on the other end.

Marked the center lines with a sharpie and Got em lined up...

Anyway.. Since those were in the correct places, that means I did the timing correctly and didn't mess with my VVT at all? Therefore, I have a stuck valve(s)?

If the timing was right and even if it combusted only once before it lodged itself, the first time I turned the key (maybe I just didn't hear it) there's still no way it could have bent a valve right?
