I was at the machine shop today bringing them my valves and they talked to me about the valve seals that I brought them. They said that the umbrella seals dont last as long as the positive seals and that the dampener inside the valve spring usually rips them up pretty good over the years. Would it be ok to run a positive type seal on these heads? Do they allow enough oil to the valves? Thanks - Justin
