+1mm piston rings

i have norris designs oversize pistons in my engine, does anyone know where to get the rings for these pistons as they dont list them on their website?

Take the pistons out and measure the rings and determin pistom manufacturer (noris use je i think) then contact them or hastings direct, mahle and hastings are the biggest manufacturer of piston rings in the world

It's either that or HKS isn't it? He seemed pretty keen or selling HKS parts has "Norris Designed" at one point.

Will prob be a week or so by I get the chance to get the engine out. Anyone know if these pistons lower the compressiion? Got 120psi +-5 on all cylinders. My rad is emptying into expansion bottle with a bit of oil aswell. Also seems to be a lot of oil leaking from where head meets block on gearbox side. Going to get head and block skimmed and rebuild the whole engine.
