thanks guys so a certain amount is normal?

I've been looking for an excuse to do a top end and go to 8:1 so not too worried if it does need new rings but I didn't want to do it for a good 6 months. I guess a leak down test will reveal all? I haven't ever done one on this engine.

I did want to reuse the cylinders, I'm hoping ring damage hasn't scored them...

Thanks for the replies.
