crashing in the traditional sense seems less likely. With a "rigid" valvetrain, if the piston hit the valve something had to give, i.e. the valve or the piston face or a pushrod or ???

It might be much less of an issue here. I still think you want some closed bias spring, probably nothing like 90lbs though if the solenoid can pull as well as push, but if the piston pushes the valve and the valve has somewhere to go then it might not be catastrophic, or it might be, dunno.
