okay I'm putting the belt back on the l67 and it's rubbing. If I put a 3" pulley on the end under the coil the belt won't fit. Idk what's wrong with it at all. I've never had this engine eunnimg before either I bought it and rebuilt it a couple months back so I assume the guy before be messed with something. Thanks.

Looking at this picture of a tensioner from Mace, your idlers are the wrong way around.
So the small one under the coils needs to go to near the harmonic balancer, the one from next to the harmonic balancer needs to go to the tensioner, and the one that's currently on the tensioner needs to become the idler.

When changing them over with other ones I had the 2 up top as 3" and the one near the balancer as 3.5" yet the belt still rubs. I have no idea what's going on

So I've realised that the picture is upside down on Mace's site and that the way said won't work due to ribbing. Seems like you've got a couple of random idlers on there, probably from the regular serpentine belt. The pulley near the harmonic balancer and the non-tensioned idler need to be swapped, but they also need to be swapped for ribbing, so you should have a small smooth idler and a ribbed larger plastic one as in the pic.

So what do I do about the the double idler near the harmonic balancer?

Scrath that too. It's almost like the bottom pulleys aren't close enough to the water pump -

That's an Ecotec with a blower on top

Anyway the bottom pulley location shouldn't change between the two because it's also a point for the regular serpentine belt which is the same on both engines. Speaking of which, does the regular belt fit? Pretty sure your bottom pulley is misaligned or bolted on in the wrong place, looks waaay too close to the A/C compressor, or it could be using some random idler bracket.

Better image -
