Yes, hard chroming will work fine.

But it may only need a little 400 wet or dry sand paper scuffing or a brake cylinder hone run through it.

Most worn model engines I've been around would have no wear ridge at the top of the sleeve. Worst case was usually a deep scratch somewhere on the sleeve.

I'm assuming it is a ringed engine. You can get a new ring from Frank Bowman. You can send the whole engine to him and he can do it all if you want.
