had my engine rebuilt ..installed a new clay smith cam..264 either 110/110 or 112/112 center lobe..just don’t remember..bought it back when that guy in az.sold parts…question is..do I need the 302 valve springs…clay smith sells the dual springs..my old cam was the 260 and I believe when I had the head rebuilt years back…he put stock springs…car ran fine…but you know..want it done right…thanks for any advice.
