I am rebulding an approx. 1981 SD1 engine for my 1972 3500S. I intend to use tin head gaskets because the CR on this engine is already as low as 9:35, but have planned to use a composite valley gasket. Is there any special problems with that? Maybe the intake openings have to be trimmed slightly not to act as a barrier for the gas? Has anyone done this with success?
