Tools? A cord powered electric drill, the higher speed the better. I think it was a 20" drill extension. A thick leather glove to steady it while you work (I put some WD40 on the extension so it would spin freely). 3 or 4 1" round stone bits. 3 or 4 1" flap wheel bits. A punch to knock the freeze plugs sideways. Vise grips to yank them out. Compressed air to blow out all the crap when you are done. I used a dremel with an extra small stone for the outer circle of the water pump (on the block). That's about it....Before I started the grinding a actually took a hammer and punched a piece of threaded rod down the center of the water passage which at least got things semi opened up. Before I did anything I could not see light at the other end even though the freeze plug was removed. There is some major restriction in there. Again, just be careful not to damage the holes for the freeze plugs, and try to stay away from the backside of the cylinder walls, they are mostly protected but it is possible to touch them a little in some spots.
