Did you actually talk to a vendor that has JE pistons for a Norton in any bore size? They seem to be as scarce as hen's teeth. I didn't look that hard though.I think I'm going to stick with the JE forged pistons with graphite coated skirts.
If you have not found a vendor that carries a lineup of JE pistons for the Norton 850, you might want a plan B piston option. The parts landscape could change some by the time you get around to taking the motor apart and stop all the talking.
Lots of copper gasket options from JSM to get the CR you think you need. I would only skim the head if it is not flat enough to seal. Ask the Jim's or your reputable engine builder what amount of error constitutes the need to resurface a Norton head. I know there is some room for error particularly with a composite gasket. Copper has some give to it, but not a lot.
