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.

Use RTV sealant to properly seal end seals, such as Edelbrock High Temp Silicone sealant #1076, DO NOT USE END SEALS GASKETS.

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.
