I think you guys are getting confused on spring pressures.

320lbs for a solid roller is nowhere enough.

Also, you can run up to 350-400 lbs on a hydraulic roller grind.

As I remember Berm, you don't have enough spring for a solid roller, but you could probably use your springs on a hydraulic roller cam. Plus you could always remove a shim or put a thinner spring locator on to lose some pressure.

I wouldn't run a hydraulic roller lifter on a solid roller cam myself.

I've ran some pretty stout hydraulic rollers and have had problems with losing control of the valve train, even with stout springs and titanium valvetrain components.

The ramps on a solid roller cam are much steeper and you take the chance of lofting the lifters.

You can run solid rollers on a hydraulic grind, but usually the lash is cut down extensively.
