Just a quick story to note: That area on the SBC head is very thin. As a youngster I tried using the wrong type of torch, a simple propane torch, to heat a stuck plug. The slow application of heat by the torch warmed both the plug and the head. The plug came out but by the time the head was done cooling there was a small crack in the cast iron.
