After break in, my brother and I have run Mobil 1 and SOPUS 5W30 Syn in many of our drag cars. No extra additives.
It depends on your application. I would say check the valve spring pressures on the cam card and call the manufacturer.

Amsoil makes high ZDDP oils; Redline is chock full of goodies too.
I would be buying an oil engineered for that application instead of trying to fortify an oil that is not.

That "imbalance" on the finished oil is ? I've used the other brand with SN oil and also, no problems.

Redline break in oil additive is well respected by some members here. It's worth a look.
I don't like the idea of adding anything to engine oil as there is a chance that the chemical makeup of the additive package in the oil can be compromised. Use an oil that has the necessary amount of ZDDP in it. Companies such as Valvoline, Amsoil and Brad Penn make oils with added ZDDP for use in flat tappet engines or you can use and HDEO oil such as Shell Rotella T or Chevron Delo 400. I've been using Chevron Delo 400 15W-40 in my Studebaker engines and in friends Chevy and Ford engines for well over 30 years with great results.
Get the Amsoil oil made for classic cars.
Zddp additives are used for break in, if you want higher zinc oil buy it formulated with high zinc already in it.
FYI most people think they need extra zinc when mostly they don't, even flat tappit engines don't need it when running stock valve spring pressure. Remember there are modern and organic anti wear additives in the oil that do their part too.

Mix in zddp doesnt seem to work as well here as a dedicated classic car-race car oil. We use here and sell Brad Penn oils with zero issues.
An off the shelf HDEO will work for almost all applications as I have half a dozen older engines/trucks and they all get 15w-40.
The only disclaimer is stiffer than stock valve springs/racing applications.
My brother has an older Porsche he tracks and uses Brad Penn, personally I don't think he needs it but it makes him feel better.
