Re: Stepping the block and O-ringing
When you step deck you leave the sleeve surface slightly higher than the outer deck of the block, its usually a small amount like .003 which aids in headgasket sealing.
Oring the block is a small groove cut around each individual sleeve which accepts small copper wire, when you torque the head down the copper wire crushes into your head gasket and helps seal everything up.

Re: Stepping the block and O-ringing
I run GE sleeves and when I had my block sleeved I didnt do the O-ring option because I was told I didnt need it, but as time went on, I noticed I was blowing quite a few headgaskets and some members on here recommended me to get the O-rings, I sent the block back and had the O-rings machined and Im glad I did, I quit blowing headgaskets.
