650 rings?

getting ready to rebuild the top end on my kz650b, I found a place that had a set of std rings a while back but seem to have lost the info, anybody got any ideas?
I will be pulling the head in the next week so so and will make sure a std set will work, but in the meantime would like to get a line on rings,
Thanks

www.loudfastugly.com/index.html has 2nd oversize rings, but no standard size, I don't know of anywhere that has standard size in stock.

You might check with Bike Bandit and Ron Ayers though.
I think Jeff at Z1 Enterprises either said he could not get them, or that they were really expensive if he could get them.
