Also, if I remove all the cam caps will the cam just pop out or do I need to take off the cam gear?

Yep you look to be at TDC. You have to remove the cam gears in order to replace the cams.
 

Yes, it looks like you are at TDC. Both alignment dowels on the cam gears(second pic) are straight up. And since you have to remove the timing belt to remove the cams, you can comfirm the crank timing mark under the timing cover before you remove the belt. You do no have to remove the cam gears to take the cams out. They will come out together.

I have new cams that need to go in, so I guess I should just remove the cam gears. I put the plastic piece between the cam gears to hold them in place along with zip tying the belt to the cam gears. Should I now loosen the 17mm cam gear bolts? I'm trying to thread the cam tensioner tool to slip the timing belt off, but for whatever reason it isn't wanting to thread in?

Sorry I understood that he was wanting to remove the cams as it is setup now with the timing belt all timed up etc.
 

I didn't realize you were changing cams, your post only mentioned valve stem seals.

Huh? You need to lock the auto-tensioner first by putting a 'pin' through both the housing and the rod, then undo the tensioner bearing to slacken off the cambelt, and that should be enough to be able to remove the cambelt, but if not you can remove the auto tensioner altogether and that will give the tensioner arm more room to swing back.

Yeah I realized that now would be a smart idea to install my cams. I was going to take off the exhaust cam first, swap out vss, then install the exhaust cam, and just switch out the intake after.

I have the rod in this tool, and was under the impression that you thread that in and that helps me slide the timing belt off.

I'd pull the timing cover. It is so easy to do with the motor out, you can completely remove the belt, and atleast you can be 100% sure you time it correctly when you are done

Whats the advantage to removing the whole belt as opposed to just slipping it off the cam gears?
 

Peace of mind that the belt gets re installed correctly. Proper alignment on the pulleys, proper tension, you can just be sure something stupid doesn't kill your investment. Plus IMO its way easier to time these engines by first placing the belt on the cam gears, then idler pulley, the oil pump drive, then crank, and tensioner pulley last.

OK, so Ill take the whole thing off, but once I take the belt off do I then take off the cam gears, swap the cams, bolt the gears back on and install the belt?
 

And use blue (med) loc tite on all bolts going back in the sprockets and pullies.
