Well,I'm not Don D,but I did stay at a Holiday Inn last night.Earl and 
Terry both have a valid point with the lifter bores and 
oil,respectively.

I'd like to make a few suggestions.First,seek out a machine shop that 
bushes the lifter bores and corrects the alignment,preferrably with a 
Rottler 67 or 68 CNC block center.CRE(they did my block) near 
Chicago,and Best Machine in MI have them.

If you can't have the lifters bushed then I suggest this.After you drop 
your lifters in your machined block,place a matchmark on each lifter and 
each lifter bore.After the valvetrain and pushrods are installed,and 
before your close it up with an intake,rotate the engine several times 
to make sure the lifters are rotating off their respective 
matchmarks.This should catch tight clearances.

Break in with Rotella T and a HEAVY zinc based additive.GM EOS is 
commonly used.After the rings have seated in,switch to a Diesel oil such 
as the Rotella or Mobil Delvac 1.However,even the new formulation Diesel 
oils are lacking in Zinc protection due to the new regs.I'd lean toward 
adding EOS to the oil at every oil change.
