So, I finally read all the way through this thread today, and I think I have an answer to one of your questions.
They look identical to Maximum Torque Specialties' 'budget' shaft rocker setup that Al Betker used to sell back in the day. I bought mine for about $400 if I remember right, and immediately after he sold the company to the two dudes from California, the price jumped to $700. Without the shaft setup, you're limited to about 4500 rpm before they start falling off the pedestals.
Just to note, the stock rods are good to 5200 rpm with ARP rod bolts, and 5000 is a safe rev limit. At 5400 rpm you will lose rods. They're well built, but 5400 is their limit. Stick to below 5000 rpm.
I have my limiter set to 4500 if I remember. There isn't any point to going that high or higher with the setup I have.
