Since you are keeping the same crank, rods, pistons, there is not much for you to measure. You did have the crank turned so I would plasti-gauge the main and rod bearings (if you do not have mics). This will let you know if you are within an acceptable range.
You mentioned wanting "real high compression" How do you plan on getting there? What heads are you going to use? Keeping the same pistons and heads, your compression is not going to change.
When building an engine there are a LOT of things to be aware of and to check. Rod side clearance, crank end play, deck height, main and rod bearing clearance, degree the cam, etc... You are assuming everything was assembled right in the first place and if it wasn't you can/will have problems. If this is a high performance build you will want to check everything (and assume nothing). Sounds lioke this is your first build, if so go buy a good book like "How to Rebuild A Small Block Chevy" there are a few different books out there. You will need them for several reasons (torque specs is one reason), they will also have the required clearances of all components.
