I am running aluminum heads with Harland Sharp roller rockers with a .566 lift. I bought aftermarket chrome stock type valve covers. They are 3.5 inches tall with the pent roof style. Will the Harland Sharp rockers clear these valve covers or will they hit? If they do hit, what mods can I make to make them fit. I already tried the Ford Motorsport Tall covers, but they do not fit in my 64 T-Bolt.
