Tunnel ram cam?!

Well YR beat me to it... just as I was typing 650 DP and the other carbs being glorified scrap metal. But with a 6000 rpm limit, I wouldn't think about anything that resembles a tunnel ram. But, if your mind is made up and the spring and retainer clearance is okay for the lift, here you go, and good luck!
