Now I know we have custom piston options for Piston to valve clearance, but do we many options for better valves, retainers and valve springs to take advantage of those cams?

Piper has Springs and retainers as well as a few other companies. the problem area is coil bind if the springs do not support the larger lobe as well.
High RPM is going to need a higher spring pressure as well for High RPM and valve float.
