I'm not sure as they are old and I have been unable to find any info on them. The #'s on the top were L3061F. They have 2 sets of notches for the valves which leads me to believe they are the low compression ones. How much of an increase in compression will I get if I go from the current stock 73 open chamber heads to say the closed chamber Edelbrocks or magnums?? Thanks in advance
