"The least amount of recorded break-in
wear occurred when the engine was ran at 2800 rpm for ten
minutes, allowed to cool, and ran again for another ten minutes.
This is now recommended for all camshafts - bushing and needle
bearing lifters, or flat tappets. "
"Today’s hydraulic roller lifters respond best to 10W-40 oil.
Many noisy lifter complaints are
actually from using the wrong viscosity. A thicker, higher
viscosity oil like 20W-50 will not flow enough oil into the lifter
and too little viscosity, like a 5W-30, will allow the lifters to
“bleed down” easily. While there is a common misconception
that performance engines need a 20W-50, results show 10W-40
provides the correct viscosity for hydraulic lifters."
"Use a finer micron filter during break-in"

These motors ran 5w30 from the factory. 10w30 was an option but the dealerships all used 5w30 for oilchanges. I broke mine in with 5w30 and have been running 10w30 every since.
