Hello all … it's time to replace my factory original 1957 364 rubber valve cover grommets … unfortunately the only one's I can find are too small in diameter and too hard and too thick …. kinda a goldie-locks syndrome The factory originals have a thin in-set washer that is 1-inch diameter and the factory grommet top is large diameter enough to encase it … the factory one is still soft and not hard like the replacement as well but at any rate this replacement grommet is too small … Also looking for a manifold gasket set that has the heat passage holes covered and built into the gasket itself .. there was supposedly a guy in n.y. state that makes them just for that purpose of sealing off the heat passage way in the base of the manifold … any help in referrals appreciated - thanks in advance - dave
