I have rear SSBC disc brakes on my 67, they have 500 miles on them. There has been a noticeable squeak from the right rear brakes. When apply brakes (manual), it stops. I have gone over that caliper and everything seems good to go.

I feel like I am missing something obvious, just not sure what it is. I believe that their installation instructions say to use to red goop, so I didn't.

What wheels do you have on it ? I found that my rear squeak was coming from the 14 " rally wheels, the studs that hold the wheel together we're very slightly catching on the calipers and causing it to squeak on the disc. Maybe put the rear up on some stands and put in gear at idle and see if you can hear it ?? Good luck

Disc pads sometimes make slight noises as they are sitting right against the rotor. Did you apply any anti-rattle remedies when you installed them?

I have 15" bullet rims. I like idea about putting in gear. Safely.

No anti rattle remedies as that was per the SSBC instructions. It seems to be getting louder... or just getting more annoying.

Put car up on stands and ran it. Definitely the right rear tire. There is a VERY SMALL side to side wobble on the tire. The SSBC kit required a shim and I had a couple extra, so swapped those out and it didn't change anything.

Rotor or tire?

And now noticed that the left rear rotor is VERY hot compared to all the rest. Brakes are killing me.

I have lots and lots (and lots) of brake experience. Designing, fixing and selling setups and pads.
I worked for the largest pad manufacturer in the world as a technical sales person as well.
SSB setups are "interesting" in their design. Their instructions suck.
You're not trying to use their brake pads, are you? I've got nothing good to say about those.
500 miles may or may not be enough to see shiny marks on the steel portion of brake pads.
These are called "steels" or pressure plates or blanking plates in the industry. Any shiny spots
you see are squeals/squeaks or other assorted noise.
You need to have pad shims on there. There should be lube anywhere the steel slides. You
should not be putting lube between caliper pistons and steel plates. Nor should any red/orange
goo be used.
Cermalube (Bendix) is one of the better ones. You want that or a moly product. Don't go crazy with
the amount of lube. If it migrates to the friction surface, you WILL have big problems.

Oh, I just noticed that caliper deal you mentioned. It could be dragging on one side due to
design irregularities or because the parking brake is partially on/not released.
The two calipers on the back of my GT (kit A110-18) aren't exactly the same physically.
Yet another reason that centering their calipers on their rotors is easier said than done with
SSB kits.

Do you have a dial indicator?
Remove the rotor and check the runout on the axle flange. If it's close to 0 put the rotor back on making sure there are no burrs or other debris on the surface that contacts the axle flange. Measure the rotor runout on the "hat" where the wheel mounts. How much do you have there?

Dial indicators are inexpensive and very useful.

Squeaking is caused by a high-frequency vibration. The "goop" dampens the vibration by stopping the pad from moving. A couple reasons why the pad might be moving are irregularities in the surface of the pad and/or rotor which can include how the rotor was machined and if it received a non-directional finish or was just cut like a phonograph record. Also, the angle at which the leading edge of the pad contacts the rotor can also cause the vibration, like chalk on a blackboard. I typically cut back the pad around the edges to a slight bevel to avoid this, too.

Sounds like a job for a mobile brake specialist, you may be able to see if the disc is running straight or any other obvious issues prior to getting a specialist around by running in gear without the wheels on, carefully !!! Hope you can sort easily as a squeak is bloody annoying!!

Just to update in case anyone else has this issue.

The install instructions from SSBC were very explicit about not putting good on the back of the pads.

So... I used caliper grease and greased the two slides (bolts), which did nothing right away. I then added just a minute drop of lubricating oil to the metal tabs, the ones that slide, on the pads. Then used a large rubber mallet to move the caliper back and forth (or in and out) so the slides engaged and hopefully got the lube worked in as well as the pads moved back and forth.

Squeak went away! I imagine something was hanging up and not sliding and the combo above was what was needed to get it moving properly.
