Chris, I don't remember the open pressures off the top of my head. How long can they hold up? As noted just above, valve springs are the big maintenance part of this engine (valve train, actually).

I wanted to try cryogenically treating the springs in the interest of improving reliability; timeline was tight (customer wanted his boat in the water this season) and so I suggested to the customer that he buy a second set of springs asap and that we send them out for treatment.
