230 freez plug removal

[stanman]

This has been driving me INSANE! I decided to put in a freeze plug block heater because at my Naper it was like $2 cheaper than one that goes in the bottom hose. So I tried to remove it by hitting it on the lip. That didn't work so I tried hitting it in the dished part and poked a hole in the plug. So a good friend of mine came over with a puller for a timing chain and used one of the things on the side

and used the lip on that and some chain to try and pull it out that way because everything else didn't work. After about three to four HARD yanks, it didn't even budge a smidgen!
So my question is has anyone ever had this much trouble removing a freeze plug out of this shinning example of fine American engineering?
P.S. This has taken place over a couple of days and sprayed it with alot of Deep Creep.
