Default 1966 389 60 bored over

I have a 389 YF engine that I just dissemble because the engine was looked ..after a lot of WD40 and weapon oil I got the engine turning by hand after removing the heads ..okay one cylinder has a rust issue at top cylinder area ..

I was thinking about letting the engine hone ..but during dissembling the engine I saw a 60 printed on the pistons ..after some search I found out : the engine was rebuilded around 2005? and only runs a short time and was sitting the last 12-15 years .. inside everything is looking very good .. bearings are nice ..what can I do now? Already bored to 0.060” ..
my machine shop said : they can hone and coat the pistons for extra material .. what do you think about ?
