Reason for this is because the big pulley was never used. The small pulley, I popped the bearing seal and packed grease in. The squeal did go away for a short period, like a couple rides. But it got liquidy and centrifugally splattered out pretty quickly.
I havent seen any indicators of rubbing but i can look again. I think putting a washer behind the pulley would put the belt out of alignment. I am wondering if i should run the pulley loose and tighten till squeal goes way, at least see if that works …

If I recall correctly, people have had issues with the quality of that dorman part. It took me years but an original ac Delco standoff showed up on ebay literally just before I hit order for the dorman part. It is possible that the fit is bad enough that pulley alignment is too far off and the belt is rubbing the outer lip and being recentered every revolution. I know some people have had to align it by putting washers between the standoff and the ac bracket with a straight edge going across the installed pulley and adjacent pulleys. Also, I know I have seen spacing adjusted by putting washers behind the pulley itself, as indicated later in this thread.
Dyrt are you an LT1 guy?
I wouldn't say I'm an LT1 guy as much as I did LT1 swap into my '86 regal limited back in 2006. My goal was always to have an LT1 with AC and a six speed, which I eventually accomplished except for the AC. When the AC pump that was running dry started making a ton of noise I started looking for a delete pulley but didn't want to use an aftermarket one since I had read so many bad things. Unfortunately without being there the best I could suggest is try to use a straight edge to go from the delete pulley to the next few pulleys. It should be relatively in line, and I read into these issues a very long time ago so unfortunately I don't have any good sources to pass to you. I would also look in the Monty SS forums as well as both 4th gen f-body and Impala SS forums. If I get a chance to take a look for you I'll pass along any links I find. The thing is no matter what belt setup you're running you want the pulleys to be as inline as possible because while they'll make up for some of the misalignment too much misalignment is just going to cause too many problems. As I said earlier I remember people spacing the whole assembly out as well as adjusting the angle by putting more washers under different spots of the pulley to level it. To this day I still can't believe that the moment I gave up hope and almost bought the dorman repro I actually found a real ACDelco delete pulley on eBay. If are you I keep looking for one. There's also another company that makes their own reproduction that's much more expensive but it does look to be a much better product. Can't remember the name of the company of the top of my head but if you look up LT1 AC delete pulley and dig enough you'll probably find it.
