Pulled the Mess that was my Timing Chain....

I think it is far more likely to wipe a cam when using a radical cam with stiff valve springs. A stock /6 cam and springs is less likely to have a problem.

I talked this over with my engine machinist and he recommended Brad Penn oil. He sells the stuff and has not seen a single failure. He told me not to use additives, just the right oil and that's it. He's been doing this since 1962 and I trust his knowledge. He also told me to change the oil at 100 miles. This is for my 225 with bore/hone, new pistons, etc.

Someone posted the a few days ago that NAPA has Valvoline VR oil on sale for $4.29/qt. This oil has high ZDDP content so you just run it straight up and not worry.
