  • 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 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.
  • Hardened washers Must be used with intake bolts to ensure proper torque and prevent galling of the aluminum.
  • H.E.I. will fit
  • Even though manifolds are compatible with EGR systems, this does not mean they are legal for use on emissions controlled vehicles. Check local laws for legality.
  • 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.
