Good luck on your project. I had my motor done a few years back and found out later what they did wrong, making my motor use oil.
You should ask your shop if they will be "plate honing" your motor and finishing your block with a plateau honing procedure. Also, the piston rings should be long lasting moly-coated. This will give you the best result for a well-sealed up, smokefree motor.
The other problem I had was a bad valve guide procedure. They nurled the valve guide in because it was cheap to do, but it was a bad idea. Most economy rebuilders use this technique. The proper way is to bore and install a new properly clearanced valve guide with a proper teflon valve seal.
Hope this helps.
