( As an aside, would pre-lube the engine with a big drill and a distrubotr drive shaft so that the 2,000 RPM after start wouldn't be dry, but that's not really possible with your engine...)
I don't know if any of that's true on your car, but be certain of the correct procedure by referencing factory (or cam manufacturer) information before the first start
Spot on advice especially for new cams with flat tappets. I don't know if the same applies to roller lifters, but i would research it.
