Old Kimmer, PM me if you would be interested in some spare parts for your stage VI's. I have a complete ported pair with port matched spacers, Hughes Valley Plate and a 4150 M1 intake. I was getting them freshened up because the valve stem seals were leaking when it was discovered that one head has a tiny crack by the valve seat that looks to be fixable. Instead of fixing it though, I decided to go with the new TrickFlow 270's as the Stage VI's are a smidge small for my 528" Springs are Isky Tool Room good to .650 and valves are all Ferrea. Rockers are Crane Gold. I also have a 4500 M1 intake that has been re-drilled and machined to accommodate a 4150 base carb.
