stock build

So, we're building a stock 200 for a '73 Benz. I was thinking of taking it to a machine shop, and having them mic it. What all should I have them get measurements for? Also, I was going to disassemble the engine before I took it there, that's what I'm supposed to do right? I've only done crate engines before building wise, so I wanna make sure I go about this the right way. We're building a dependable daily driver, so I was gonna get a master engine rebuild kit and go from there. I have all the torque values for every bolt in that engine. The pistons will be marked for what the current bore is, right? If it's the stock bore (engine never been rebuilt), what's the most I can take it safely? If it's never been touched (1970 Maverick engine), I will just bore it 10 over and get 10 over pistons. That would be the best way to go, right? Smallest bore possible? Does any work need to be done to the crankshaft ever? The master kit comes with a new cam, timing set, etc. With rod/main bearings, will the bore be on those as well so I know what to get with the new set? I'm basically asking how to select bore sizes for the different parts of the engine, in a million different ways. Thanks guys!

Also, what's a good piston ring installer? I don't wanna mess anything up on this, because this car and my mustang are the only two cars that me and my bud have to get to school, and since he drives delivery, this 200 basically just needs to be bone dry reliable.
 
First off hows your budget? Everyone on here will have there own way so take my advise for what it is worth... you need to pull the motor/block apart including freeze plugs and oil plugs out, all the shop needs, is the block, crank, rods and pistons (all removed from block to save you money), have the shop, check the crank, polish or regrind it as needed, check current bore on block, so you'll know what size overbore pistons/rings and bearings to order, you may have trouble getting 10 over pistons, but 30 over is no problem, if you have the money have the shop check your block surface trueness and surface if needed, when you bring in your parts also bring in all your tin work, front cover, nuts/bolts so when they hot tank/spray cabnet the parts they can clean these parts also, they will need your pistons and rods so they can remove (press off your old) pistons, install new ones
 
I pulled the motor apart. Metal shim head gasket, standard bore pistons, standard rod/main bearings..... it was awesome. =)))))) This motor is 30 years old, and has never been touched internally! It looks like the build has a while longer until we get it done, since he destroyed the front end of his benz today. We're gonna have to fab up a whole front end. Oh well! Thanks for your input that's all the information I needed. =)))
