If there was a small question in terms of engine overhaul of the small

Has anyone ever had their engine completely overtaken? So with hones, new coating of the treads, new pistons, etc.
The question has come to me because in recent times so much about carbon flasks is buzzing around in the press and I want to get a replacement engine for all cases.
The fat guy had some surprises for me when I got him last year.
And it is not returned,
