I'd suggest having the head pressure tested to be sure you don't have a leak into the cooling system such as an internal crack, etc. Ditto for the block, but that can be checked by simply pouring water into the cooling system with the head removed. If the crankcase is filling by simply pouring water into the cooling system, you've got a HUGE leak somewhere!
Where are you located in Alabama? I'm in south Tennessee, just above Huntsville.
