This addendum addresses those special issues that apply specifi- cally to the 351W manifold. Professional Products 351W intake manifolds have a 12-bolt intake manifold pattern, but they can be used on 1974 and earlier small-block Ford Windsor heads having a 16-bolt pattern.
How much torque should intake manifold be?
Intake manifold bolts and head studs/bolts have to be torqued in a certain pattern and to a certain torque spec in order for your engine to work properly. Intake manifold bolts on SBC engines should be torqued to 30 lb-ft in a two-step sequence.
What are the torque specs for an exhaust manifold?
Amount of Torque The standard is to use 20 to 30 foot-pounds of torque. Older engines often fall on the lighter side of the equation, so use 15 to 20 foot-pounds of torque if your engine is 15 years old or older. Some manifolds house different sensors and plugs, such as a check valve or exhaust plug.
