What engines are C4OE Cylinder Heads from? Im guessing they are 289 heads? I found some with 1.84 and 1.54 valves that have been worked and cut .010 with 54CC chambers. If I put these on a 302 will I need pistons with valve reliefs with...say a B-cam Under .500 lift? I am doing a budget build just for my little convertible. Any info appreciated... thanks!
