I used my acetylene torch today. Heated to red, came out with no problem. Thanks for the suggestions. I Wasn't too worried about heating them, just  worried about throwing cold water on red hot cast iron.

I used a small enough drill to still use the allen socket, and heat was from a small propane torch.

After you drill the holes in them do you use an "easy out"? When you say "a little heat" is that propane heat or oxy/acetelyene heat?

Same here Timbo, make sure you do not melt the edges of the Allen socket.

Drilled holes in mine, a little heat and presto!!

Another way is to drill a hole through them then get them red hot. It won't hurt the block.

Tried to remove mine years ago and never had any luck. Tried again and still no luck. Local part/stock car engine builder guy says heat them red hot with a torch, splash water on them, come back in a few minutes and they will come out easily. Says he has done it thousands of times with no problem. The thought of that scares the hell out of me for some reason. I see cracked cast iron block for some reason. This guy has been arround for not quite as long as I have and normaly knows his stuff.
