I bought a couple sets of intake spacers for my smalls blocks because with the raised runners of some of the better flowing intake manifolds my valve cover were laying on the intake instead of the valve cover rails and leaking badly. I really like these spacers but they need test fitted and some pushrod clearance grinding. Also some of these valve cover have the mounting bolt angles off small so that needs matched to the spacers. I black silicone these right to the head and then lay my gaskets and valve covers on.
