My 383 has a set of headers on it, brand unknown. When I last removed them, the exhaust gaskets pretty well crumbled, so I purchased a set from the auto parts store. Problem is, they leak now. The new ones are thinner than the old ones. Does anyone have a source for 'extra thick' exhaust gaskets? If not, should I double up the standard gaskets?
