Rotella and other diesel oils have a lot more ZDDP than oils for gas engines. I would at least break your engine in with one of those oils, and maybe run it even after break-in.
I agree on the rocker arm ratio. I was mostly wondering if there would be any benefit to going with a slightly lower ratio, like 1.7. I don't think there is any binding, but would a lower ratio be good peace of mind?
For the oil, do you think shell Rotella T 10W30 would be a good choice? Would I still want to add the ZDDP additive? I plan on calling Tim soon to confirm all of this, but like hearing everyone's input
