I have been building a 02 6.0 block into a 408 stroker, with an L92 truck intake. I feel like an idiot, but I purchased the front and rear cover gaskets and seals already and now I can't find just the head gaskets. I can find them in sets, but not separately as I already have all the rest. I am looking for cometic .040"/ 4.035" bore, intake, throttle body gaskets. If someone could link me or send me in the right direction, I would be thankful.
