No mate, they won't fit.
It's for my race pistons.
Got them 20 odd years ago in a load of ex race z9 stuff.
Couldn't find any rings to fit at the time so machined the grooves to take the H**** ones.
Only did a few hundred miles on them then changed plans.
Been boxed ever since and have decided to bring them out of retirement for the cafe racer motor but somehow one ring has lost about 5mm off one end.
