New Process - the easy way to remove factory (spiral) roll pins
The easiest roll pin removal video you'll see this year guaranteed. Anyone who has attempted to remove these buggers with stainless steel screws knows exactly what I'm talking about Also to re-emphasize the process on the video - Use ONLY STEEL RIVETS.

Great idea. I might suggest practicing with a spare roll pin first to get a sense of how much or little force is needed to expand the tip just enough to hold the pin.
BTW, when & how often do those pins need to be removed?

Most GOOD engine builders R & R them at each rebuild to allow gallery cleaning. Not necessary for just a head gasket.

I was wondering what happens if you mistakenly over press the tip and you can't pull either out?

The tolerance (clearance) between the outside diameter of the rivet and the inside diameter of the roll pin is so minute that it's practically impossible to expand the rivet to the point that the roll pin becomes lodged without popping the rivet first. In the event the rivet does pop carefully drill the face / flange of the rivet down to the body and tap it into the oil passage with a punch. Remove the pin as before. Note: Besides being stronger than aluminum here's the second reason for using steel rivets; the remaining piece can be retrieved with something magnetic (i.e. scribe, slender screwdriver, etc.).
If the block is actually out of the car then a shot of air (tape the remaining holes) should dislodge the piece. Air is not a good choice if there is still oil in the passages - things might get a tad messy.
