Re: 327 Manifold Gaskets

I have had similar problems with the gaskets that are the same on both sides with a metal core. Of corse the correct torque is very important as well as to re-torque after the engine has been warmed up and run a wile. Also checking the manifold for flatness and re-surfacing if needed is important.

The best gaskets are the ones that are metal on one side and gasket material on the other. The problem here is that the intake/exhaust manifold is very long and expands and contracts every time you drive the car by quite a bit. The manifold scrubs back and forth and wears into the gasket destroying the gasket thus causing leaks. The gasket with the metal on one side provides a surface That can take the constant rubbing without deforming. The metal goes towards the manifold.

Bottom line is I don't use the gaskets unless they are of the type that has metal on one side.
