Break in procedures?

Did the roller tappets come with any viscosity recommendations? I like VR-1 SAE 30W or Shell Rotella T-1 SAE 30 with Lucas moly break in lube or Rislone along with a WIX or NAPA Gold filter for break in. But what brand of lifters do you have? Some manufacturers are fairly specific on oil viscosity and some don't specify anything at all.
