Hi Gary, Where are you placing this gasket ? The gasket to seal the exhaust pipe to the exhaust manifold connection ? Or a gasket to seal the exhaust manifold to the head ? If you are placing a gasket at the head, I guess you can but I am pretty certain that originally there was NO gasket at the exhaust manifold to the head connection. May seem like odd advice but try putting it together WITHOUT a gasket between the Head and the Exhaust manifold and see how it seals. I am sure that others with far more knowledge and experience will reply. Sorry but I do not have a spare exhaust manifold. Good luck and happy 300'ing.

Over the last year I have developed leaks in the dr. side ex. manifold. This is the third time. Changed the gaskets twice, going on three. Sat. morning the paper , had some REMFLEX Ex. gaskets advertised that "guaranteed" not to leak. Anyone had any experiance with these? Now for the big problem!! While removeing the manifold tht bolt hole broke off the end of the manifold. Does anyone have a spare driverside ex. manifold casting ,for a 413 crossram??? I have it at the welders, now to try to fix it , but would like to have a good one as a spare, in case the weld does not work out. I had Felpro and a summit all copper gaskets and all leaked some. Gary in so.
