Since I haven't torn apart my blown motor yet, I'm not sure what caused the bottom end failure but I'm pretty sure it would have lifted the heads if the bottom end didn't fail.

What psi was your rotrex build making when it lifted the heads?
22.5psi

There's lots of guys running 16 psi or more. Do the heads lift over time? I wouldn't think so. I'd imagine it's discrete.
