I have used a stud puller to get recalcitrant studs/bolts out and it works
well. I have several different types and all seem to work well. Put a piece
of cardboard over the bolt so you don't scratch the deck.
Go to Sears or a good parts store and buy 3" round scotchbrite pads to use
in your electric drill/die grinder to clean the deck on the block.
Make sure all water passages are clear.
