   The assembly lube isn't going to stick around on oil-submerged parts for   
   more than a minute anyway after the thing is operating.  So long-term   
   issues like ZDDP content should not be a problem.   
      
   You ARE going to fill the crankcase up and cover the cams with oil before   
   starting up, right?  You're not going to rely entirely on the assembly   
   lube for lubrication until the oil pressure builds up, right?   
      
   So I wouldn't worry about it, I'd just use a motor oil with a lot of ZDDP,   
   or a motor oil with a ZDDP additive.  I think Rotella T is a good choice   
   for break-in even if you're intending on moving to a synthetic oil with   
   a ZDDP additive later on.   
      
   I see assembly lubes with all kinds of stuff in them.  I don't see any of   
   these as being a real advantage but if it makes you feel better to spend   
   an extra five bucks for an assembly lube with zinc in it, it won't hurt   
   anything.   
      
   When those roller-cam engines were new, people were using things like   
   vaseline and used motor oil for assembly lubes.  Or white lead mixed   
   into lard.  Anything you can buy today is better quality than what the   
   engine was originally built with.
