I don't think I still have 'em. Engine had 180k. From what I've heard, if you have over 100k on a motor you'll need a bore and oversized pistons. Otherwise you can re-ring yours and see if you can get away with it. Problem is the cylinders get "egged" or egg-shaped. Mine were 4.000 one way and 4.003 the other.
I'd pick up a set of 4.005 pistons if I were you, then you have flat tops and you can shoot for your 10.25 or 10.5 CR. But you'll need a couple grand for all the parts.
Or you can trade the motor plus $1200 to your buddy like I did, for a 70k mile LS6 engine, and just put in a cam and rock n roll
