Re: Interesting article on ZDDP in oil
Longtime Amsoil customer here: I don't see much if any benefits of using zddp in Model T oils aside from break-in. My rebuilder gave me a vial of it to add to my conventional oil for break-in. My engine broke-in at about 90 miles. You could tell: the engine temp dropped about 20 degrees once the rings set and things smoothed out. Unless you are running some high tension valve springs, I can't see the stock valve springs causing accelerated wear on the tappets and cam. I use Amsoil 10W-40 in my 26 Touring...but I buy it at wholesale prices and my car leaks very little. That makes it a whole lot more affordable. If things were different, I would be looking at other alternatives.

Seems like a little dab of STP, which has zinc, will go a long way for T's.

Kevin has pointed out that ZDDP has a beneficial use where valve spring pressure is high; that is not a T.
As far as STP being a benefit, I would warn that bands often react very negatively to any type of friction modifier or viscosity enhancing/reducing additive. Not something I would do, personally.
