It's probably tight plus 1 turn. I'll have a look in the manual tonight and post again if you haven't gotten a reply.

Yes, tighten to zero lash, then one turn.
The older 235's needed an extra oil line added from the oil gallery to the valve cover. The had trouble getting oil back up top. Don't know if the newer 250's were the same.
