I mentioned below about how a 39x valve could gain so volume by using a carefully crafted execution of the DORCV setup.
Actaully thats an unintended benefit, the primary being a checkvalve that didnt have the deformation issues thata the factory bit does. Especially in my AC build,
When Steve first mentioned it, the 39x setup was the first thing I thought of. Seems perfect for that......
