<<  My thinking is that if I can get things right on the ground, I'll have
less of a problem in the air regarding sealing the baffling >>

It has been said a thousand times, and worth repeating that the break-in time
spent on the ground should be kept to a minimum, consistant with leak checks
and to ensure max performance before commiting oneself to flight.  Ground
running an engine without proper equipment is a sure way to damage that "new"
engine.  Please don't get caught up in seeking absolute numbers for ground
temp's.  Ensure the baffling is tight, and that every molicule of air entering
 the front is forced to cool the engine and is not wasted through spaces
between the baffling and the engine or cowl.  If sealed correctly and with a
vengeance, it will provide adequate cooling in flight, but don't forget that
the temperatures will be elevated until the engine "breaks-in" and life
becomes good.  Also:  Keep thine airspeed up and the temps will stay
acceptable.  (No poet here)...
