Antique Firearms - Assembly/Disassembly by David R. Chicoine is what you're looking for - has disassembled gun blueprint as well as the necessary assembly/disassembly - pg. 451.

On the head spacing, you can get Clymer Go/No go gauges from Brownell, Sinclair and other gunsmithing sources.

Excellent thank you very much for the information.
