- Hardened washers Must be used with intake bolts to ensure proper torque and prevent galling of the aluminum.
- Sealant must be used on intake bolt threads if the threads extend into lifter valley or coolant passage.
- NPT/Pipe thread fittings require the use of Teflon tape or paste on threads to ensure a proper seal.
- DO NOT OVERTIGHTEN NPT/Pipe fittings, this may cause the aluminum to crack around the fitting boss. NPT/Pipe thread is a tapered thread.
- To ensure maximum performance and a proper seal, Edelbrock gaskets which are specifically designed and manufactured for use with Edelbrock parts must be used.
