You absolutely MUST consult a factory service manual for your specific year and model Dodge Dakota. This manual will provide the correct torque specifications and the proper tightening sequence. Using the wrong torque can lead to head gasket failure, warped heads, or even cracked engine blocks.
Trying to find the information online without specifying your truck's year is unreliable and dangerous. A service manual is a worthwhile investment for any car owner who performs their own maintenance. You can usually find them online (in PDF format) or through auto parts stores.
