They are also specific to use the green stuff, penngrade break in oil. They have a couple other substitutes but the green stuff is there first choice and I can see that's what they already had in the engine.
It's been run on the dyno already with penngrade and I would imagine rings are seated and things are already happy, but they want a break in procedure done anyway and this is a roller cam engine.

Probably overkill at this point but doesn't hurt anything either.
What are the other substitutes they recommend?
