Using the correct torque specifications is important. Not enough torque and your bolt will be in a position to absorb the “hits” versus simply transferring the load when there’s not enough clamping force applied. Too much torque and you risk damaging threads and causing other sorts of headaches.

Note: Be sure to lightly oil the bolt threads for proper torquing specs for bolts not in the water jackets, otherwise use liquid thread sealer for the bolts that are in the water jackets (bottom ones). 

Torque Specs - Cylinder heads

Cylinder Head to Engine Block (Standard Bolts 1972-1992)

  • Step 1: 55-65 FT/LBS
  • Step 2: 65-72 FT/LBS
  • Use tightening sequence as illustrated above

Cylinder Head to Engine Block (Flanged Bolts 1993+)

  • Step 1: 23-35 FT/LBS
  • Step 2: 45-55 FT/LBS
