Oh Geesh, you broke the number one rule of not letting the magic out of an LS - ‘never look at the cam bearings’ lol.
FWIW, I do as well. If you have any love for the motor, then you have to, otherwise your old cam bearings are a ‘loss of oil pressure time bomb’. From the looks of the pistons (that I could see) you probably don’t need an overbore, but rather just a hone job with new rings. But I know that is hard for most to do on a 250k mile motor. Hopefully whomever is installing the cam bearings is very familiar with this job - it’s not as straightforward as an old school SB or BB Chevy/ford.
Also, pay close attention to the barbell, cam plate seal and oil pickup tube o-ring.
