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 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.; Proper installation is the responsibility of the installer. Improper installation will void your warranty and may result in poor performance and engine or vehicle damage.
