Magnum 5.9L rebuild data

Hi

delivered my engine to the shop, and to check everything they are asking the all data I can provide, like the torque for the tightening the bolts (sorry for my non technical English), the diameters, all the data that will help to determine the issues I have (if any) with my crate and crankshaft, etc.

And, if possible, I'm already know that I have problems with 1st and 8th cylinders, what will I need for the next from stock "repair"? Don't laugh on me, we have "hands" but have no knowledge about this engine. Is there a rebuild kit for my case? like rebuild pistons, chain, etc?

Thanks in advance!
