Have a 1966 MM M670 tractor with gasoline engine. Noticed exhaust leakage between the cylinder head and the exhaust manifold. Removed the manifolds and it appears that all four cylinders leaked. The gaskets likely are several decades old. There is erosional/corrosional damage to both the cast iron manifold and the mating surfaces of the cylinder heads. The NOS gaskets I have are 0.040+ in thickness, however, I am questioning if that will be adequate to fill the gaps. Do I use high-temp RTV sealer on both sides of gasket? Or is there a better means of ensuring a reasonably long-lived seal? I'd appreciate hearing of your experience in dealing with this issue. Thanks . . . Chuck
