It's been over 10 years ago that I had to pull the pipes on my former ERA, and I do remember it being a pain. The key is to find a way to provide constant downward pressure while hitting them with a soft mallet. If you can find a way to provide some substantial vibration to them while applying the downward pressure, they should come off even easier. Maybe an air chisel without the bit in it or something like that. Al those tiny movements add up in no time.
