The last bottom end I did (352) also needed ridge reaming, but it had
a lot more time (miles) on it. *That leaves substantial shavings.
I didn't notice metal from doing the crosshatching, but the hone
leaves grit, which is no better.
A good blasting with compressed air around the gap should blow it out.

Sorry, I'm still thinking that honing a cylinder with the piston in is
not a good idea.
