This is certainly an impressive list.... I'll just add one comment - a lot of what you were trying to clean up is varnish related. Even the ticking lifters could be a varnish deposit in a bad place. Even during the "can do no wrong" heyday of ARX here, it was constantly stipulated that it wasn't the tool for varnish and was not effective against varnish or staining.
It would not surprise me, since it was stated repeatedly, if ARX didn't do much for your varnish.
OK, two comments

It's also been said before that there are a lot of stronger/quicker products that will do some of what ARX claims to do. If you're dealing with a sludger, there is some danger in working too fast and this was a niche that ARX was marketed towards. (yes I'm choosing my words). 5qts of kerosene will clean up a sludge problem pretty quickly, but there may be lots of ongoing issues and possibly blocked passages.
This is not to say that I don't accept the fact that faster products may be the way to go for some things. I'm tempted to try something "faster/stronger" before my next OC to see if the lifter will straighten out. I have a bottle of Swepco 502 someone gave me and I've googled a lot of people with good results using it for lifter noise.
