I have an old pieced together SBC, the bottom end has never been touched, but I threw some heads and a cam that I had laying around in to get the engine together and in my truck. The cam is a hydraulic flat tappet and the springs have high enough seat and open pressures to, in my opinion, “require” an oil with elevated levels of ZDDP. Would it be wrong to try and use restore and protect with some sort of additive in this engine?
