To line2line coat or not to line2line coat ;-)

Next size piston I found was 4.382", so I assumed I need to bore 0.007 over what I have now.
Frankly I have no idea what piston clearance I need, never bored a block and machine shop always handled this for me.

I discovered I have scratches in all cylinders using inspection camera. It does not need much oil, does not smoke, no blow by, has very even values from compression test, but it just pisses me off. I'm living with this for a while now. Does not seem to worsen but you know, car will be sitting because of winter so I may just do this and sleep a bit better... ;-)
