Interesting that you are choosing to go with the limited cast 4V heads. (Exhaust side mainly) I was running E85 with 13.5:1 but got tired of looking up where to get it and then consistency of ratio. finally gave up, installed dish pistons so I would not have to change my aluminum heads which have many hours of flow bench work. lost over a hundred horsepower but I can get gas anywhere! Down to only 670Hp now. ok for an old street car. As the Bossman knows those 4v heads Intakes like rpms but the exhaust side doesn't and becomes a compressor. Just a thought.
