What is the bolt tightening pattern on a 318 head?

The bolt tightening pattern for a 318 engine head typically follows a specific sequence to ensure even pressure distribution. Generally, the pattern starts from the center bolts and moves outward in a crisscross fashion, usually in a 1-2-3-4 order for the first row, and then a similar pattern for the second row. Always refer to the manufacturer's specifications for the exact pattern and torque values, as this can vary slightly by engine year and specific model.
