Use a break in oil with high as in 1200-1400PPM ZDDP,Manditory with flat tappets and a good idea with rollers ,Use an oil with little or no Molylebdenum as it will impead ring seal on break in and too much moly will cause needle bearings to glide instead of roll making flat spots with high spring pressure aggressive cams.Best way to break in new engine is on dyno with blowby meter.No synthetic till after break in.Bill C.
