if you cant find the +30 than order +40 and file fit.

If you can't get them from Norvil, I might have a set in the garage. They would be for early Powermax pistons that have a shallow oil ring groove though.

thanks but these are the stock JCC pistons, normal oil groove. Do the Norvil rings have a 3 piece oil ring

I've never seen JCC pistons for 750 Commandos in anything but standard, +.020, +.040, +.060. and +.080. Could be they made a special run for someone like Norvil, but I doubt it.

Might be GPM. They made +.030 at one time.
