Cotton: What ever do you mean?
Want to hear somthing interesting? Just found out my old high port dual carb heads and jugs off my old drag bike will fit the VL cases,pushrod angles are better than on shovel,these heads flow 200 cfm at 10" ,with rocker arms the stock VL cams will make .536 lift and may be a little more duration. WaaaH !! another option
Ps We went 9.08 et at 153 mph in quarter on alky with these heads
