Kevin, The heads are big port 3.0 SC heads. Steve Weiner & Jeff Gamroth did the heads about 2 years ago. Intake valves have 8mm (7.96mm) stems and the valve size is 51mm, 2mm over stock. Exhausts are also 8mm stems and stock 41.5 valve size. Idea was to have less weight. CC'ing the heads and also getting a theoretical cylinder volume.
