The threads in a cast iron head will be trashed if someone is stupid enough to continue to thread the chaser in even though it is taking too much torque. Most guys will have sense enough to stop as soon as they feel any undue resistance. At that point, the other options should be explored.

The internal chaser is used from the inside out, w/the head on the engine.
