valves?
Did you have bigger valves put in the stock heads? If not, then you won't see much of a difference with a bigger cam. The heads are still choking your combo if the stock valves are in there...even if they are ported. As for which cam...I couldn't really tell you. An E might give you a little more performance. Stay small though. Or wait until you can get some better breathing heads with bigger valves and then install the cam. Just my opinion...
