What is the head torque for a 1985 ford f-150 300 straight six?

There isn't a single, universally applicable head torque specification for a 1985 Ford F-150 300 inline-six. The torque specification depends on the specific head bolts used and even the material of the head gasket. You absolutely must consult a repair manual specific to your 1985 Ford F-150 with the 300 cubic inch inline-six engine.

Using an incorrect torque specification can lead to:

* Head gasket failure: Too little torque won't seal the head properly.

* Cracked cylinder head: Too much torque can crack the cylinder head.

* Stripped threads: Over-torquing can damage the engine block.

A reliable repair manual (like a Haynes or Chilton manual, or a Ford factory service manual) will provide the correct torque sequence and specifications for your specific engine. Failing to use the correct information is risky and potentially very expensive to repair.
