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.
