Finally decided on a cam for teen SB. Should I bother with header?

Who cares about numbers? Drive it. You'll be happy with it because it's a good combination. That was a smart cam choice.

This^^^^^…… Pump that cylinder pressure up. If you decide to do long tube headers eventually, these cams WAKE UP with pipes & head work. It won't run twelves,a damn good balance of torque & gas mileage.
