Two Valve Head Cam Intake Upgrade Bolt Torquing
|
The stock head bolts are torque-to-yield and cannot be reused. You can get stock replacement head bolts from Ford Racing Performance Parts or your local dealership, just make sure to follow the directions carefully. Usually the process is to torque all the bolts to 35 lb/ft, turn all the bolts 90 degrees, and then turn all the bolts 90 degrees again. If you plan to make more modifications to the engine and might be taking the heads off in the future, it's usually worthwhile to invest in a set of reusable head bolts from ARP. View Related Article
