5.3 to 6.0 LY6 swap 09 GMC Sierra
as some of you know a blew the 5.3 and bought an LY6 6.0, well, today as i was cleaning the engine and checking the block/ rotating , i found that the pistons have some very low but noticable play when you push them from front to back,
also the rod bearings look like they have a little ware , should i change that too?
the last thing is that the first cam bearing have copper colored spots, change or leave?
here are the pics:
here is the cam bearing
bore was smooth with no signs of ware
the block was in great shape acctulay very slight rust consdering its a 2008 and the junkyard was close to sea!
so what do you guys think?

CYlinder walls should be honed and new rings installed on the pistons. Some people have successfully reused original rings but the chance that they dont seat is too big for me. You can get a factory set of rings for 150, cheap insurance.

89017484 is the part number,
its for 30$+ each, in our dealerships ,the only one has them in stock sells them for 41.35$ and thats for each piston, and they only have 4 piston sets !!
waiting on fel-bro dealer to get me the new ons
he said he can get me some perfect circle rings set for 8 pistons for 95$
they are made in India , are they trust worthy?

is it ok to use a 400 grit flex hone to do that by my self?
they say that 15-20 strokes with that will give the same result as a machin shop,with 1/2 the cost and faster
