* Head bolt type: Are they standard bolts, studs, or aftermarket high-performance bolts? Different materials and designs require different torque specs.
* Head gasket type: The type of gasket used can influence the clamping force needed.
* Condition of the engine block and heads: Worn threads or damaged parts can affect the proper torque.
You absolutely MUST consult a reliable repair manual specific to your 1979 Chevy 350 engine. The manual will provide the correct torque specification for your specific engine and the components you're using. Using the wrong torque can lead to head gasket failure, warped heads, or even cracked engine blocks.
Where to find the information:
* A shop manual: A Haynes, Chilton, or factory service manual for your vehicle is the best source.
* Online resources: Some reputable online automotive parts websites might have torque specifications listed for specific parts but always double-check with a manual.
Do not attempt to torque the heads without consulting a proper manual. Improper torque is a common cause of serious engine damage.
