Just measured the bores on a 400,000 mile LQ4 & was close to PERFECT, It is getting a 4" stoke crank & will only need to be Honed a few thousands with new standard bore forged pistons which are actually a little oversized!
Comp Cams is a JOKE, Call Cam Motion for a custom grind which are A LOT easier on valvetrian components including the lifters. I build all my LSX engines with LS7 lifters.

most of these kits wear out the brass/bronze bushings in short order. Especially on a L92/LS3 offset intake rocker
for stroker consideration, if it needs bored, then you are buying pistons and might be halfway there to a rotating assy. Makes it a tougher decision....if the crank is bad and you need a crank anyway...then makes it easier.
most likely from what i can see in your pics, you don't need to bore the block or change crank. You can have the hone touched up and re-ring it, re-use everything else.
Put ARP bolts in the rods, fresh main and rod bearings...let it roll. You'll never have to take it apart again for a refresh.

Do the new rockers fix the problem with the side cams coming off and the needle bearings ending up in the pan? I am running the 317 heads so I don't need to worry about the offset rockers.
My wife would like the idea of just honing it and putting it all back together and run it. lol Way cheaper of a build.
