I have ad my manifolds off twice now to replace the manifold gasket. right now i have the clifford duals and the stock intake on the motor. the last two gaskets were felpro. which gasket can i use to keep this from happening again? i think there are least four cylinders leaking right now. and the collector gaskets are pretty much gone too, so i will have to replace those as well. thanks for the sugestions.

Both Clifford and the Cox boys have a thicker material I/E gasket for the SL6

Also check the header flange for flatness, it may be bent / bowed to the point were nothing will seal.
