Incorrectly tightening bolts is the fastest way to warp an aluminum cylinder head. Relying on precise instructions from a digital document ensures proper clamping force:
Loosen the cylinder head bolts in a 3-step progressive sequence, working from the outside of the head toward the center. This prevents thermal stress deformation of the aluminum head casting. Installation and Torque Specs
