I have a set of 510 SSS SU's on my 86 Accord project, I'm getting to the point where I want to go ahead and get them overhauled as I want to start the car in about a year, I was looking for recommendations on a rebuilder, so far the word seems to be Z therapy, I was wondering if anyone has feedback on them etc, as this is going to be a big chunk of change to get these done

You could try this place

I mentioned them in the first post, I was looking for feedback on them as well as anyone else, it's a long story on the project, which I will eventually post, I went from a horrible electronically controlled keihin downdraft carb,to a set of these Su's ,it's been a very long three year project on this car so far, I've owned it 15 years

Sorry I guess I got the cliff notes version of your post. I have not used Z therapy myself but the people I have spoke with about them say they are great.

They have rebuilt 4 pairs of SUs for me. All worked flawlessly. I would use them again tomorrow if I needed another set done.

They aren't cheap, but they are the best.
