Tunnel port intake manifold

Does anyone know the bolt torque requirements for the tunnel port aluminum 4V intake manifold? I know that it is less than the standard FE intake torque of 32-35 Ft-Lbs. Thanks

Re: Tunnel port intake manifold

The normal torque for an FE intake is 35lbs. Edelbrock recomends 25lbs. on their aftermarket intake. If you torque to 25 and run the engine and there is a vacuum leak retorque to 35. Use right stuff or RTV on the front and rear of the block to prevent seapage and to ensure a better seal.

Factory spec is 23-25 ft lbs. What kind of intake gaskets do you have? Ford oem, Mr Gasket, other?
