    I think you'll be lucky if they have them in stock

      i think they have their information wrong. S2 ABY does not have 10:1 compression ratio. It has 9.3:1

        Try wossners via PEC. They might be able to turn something around quick. Personally wouldn't touch Omega with a bargepole as had some bad experience in the past with valve cutouts being too close to ringlands.

            Run them reliably over 600 in a 5 pot wouldn't fit them to a 800+ project but no issues for 6-700
