Use RTV sealant to properly seal end seals, such as Edelbrock High Temp Silicone sealant # 1076, DO NOT USE END SEALS GASKETS.
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.
Carburetor size (CFM) should be selected based on your specific engine combination.
