Is this a silly plugs up engine Ed? You know how I feel about those :-)

If so it is probably not bled properly. There needs to be no trapped air 
inside the block. It is going to be real hard to insure that with a plugs
up engine. Mazda put the inlet and outlet on the block where they did
for a very good reason. They are near the top of the block so trapped air
is released. If you rotate the block all bets are off. Sheessss!
