What should intake manifold bolts be torqued to?
Intake manifold bolts on SBC engines should be torqued to 30 lb-ft in a two-step sequence. First time around, set your torque wrench to 20, follow the pattern, then repeat the pattern (image above) again after setting the wrench to 30. The image above shows the torque pattern to be used when reinstalling the heads on any SBC engine.
