AMC360 build with 343 Rebuild Kit

This is more or less a repeat of this build thread but this time, we are using a complete off the shelf 343 rebuild kit from Ebay. This one is for ELRonDeCuba going to France.
Again, the idea is to use off the shelf 343 flat top pistons to boost the compression ratio just below the magical number of 10.0:1 to be able to run on regular old pump gas.

This is the kit that I bought off of Ebay.

This the actual kit.

The first key things that I had to do before ordering the kit was:
1. Select a pair of cylinder heads with the largest combustion chamber (63cc) so that I can keep the compression ratio below 10.0:1. Cylinder heads casted from 1978 and later have the 63cc combustion chamber.
2. Determine what over size pistons were needed.
3. Determine what under size Rod and Main Bearings were needed.
