How can I improve this Cobra?

[razerwire]

Looking at my trigos the valve stem is in the spoke area, however My halibrand mags have the valve stem in the rim area. Halibrand say cobra2 on them front and rear side. I have 3 sets of halibrand spinners and they all have halibrand on face of all three ears. Back side of ears, one has 6061, one has H326A, and looks like alcoa. Hope that helps to identify what you have. Why not go to 8 stack fuel injection, have twm on shelby and going to put on Bennett car because it works so well on shelby. Pulling engine soon on Bennett car to refresh and will have Rex at Engines by Rex in Sacramento change out sidewinder intake and install twm intake. I have been real happy with twm, idles at 800 rpm and can short shift to keep noise down if need to and engine will pull with no cough from low rpms.
