exrodder Blue is
oil if this is the color. It sound like extra clearance in the guides and the valve is bending and sucking the
oil into the chamber. Send heads out for repair and tell them you want the specs on valve clearance first. Buy a set of Edelbrock alum heads. Fix the old heads. Send them to George anderson at Guessford machine. You know that he will do you right. I can give you the blueprinted numbers for the valve play. I don't have them right now but if you want them I will dig them up. I think they make oversize valves for your heads. .003-.005.-.015 or at least they used too. Stay in touch. Rick Lake
