* Specific Cylinder Head: Different heads (e.g., casting numbers) may have slightly different specifications.
* Head Bolt Material: Are they original bolts, or aftermarket replacements (e.g., ARP)? Aftermarket bolts often have different torque specifications.
* Head Gasket Material: The type of gasket used can influence the torque procedure.
* Torque Sequence: The order in which you tighten the head bolts is crucial for even clamping pressure. This is *not* a simple "tighten in a circle" process.
To find the correct torque specifications, you MUST consult a service manual specific to your 1993 Chevy 5.7L engine. This manual will provide the correct torque specs and the proper tightening sequence for your specific engine and its components.
Don't rely on general internet information for this critical task. Incorrect torque can lead to warped heads, blown head gaskets, or other serious engine damage. A factory service manual (or a reputable online equivalent like Chilton's or Haynes) is essential. You can often find these manuals online or at auto parts stores.
