You absolutely must consult a factory service manual for your specific vehicle. These manuals provide detailed diagrams, torque specifications, and the correct tightening sequence. Using incorrect torque values or sequence can easily lead to warped heads, blown head gaskets, or other serious engine damage.
You can find factory service manuals online through sites like eBay, Amazon, or Helm Incorporated (the official source for many manufacturer manuals). Searching for "2000 Dodge Ram 1500 5.9L service manual" should give you several options.
Attempting this repair without the proper manual is strongly discouraged. The consequences of improper tightening can be expensive.
