The Cobra is a good intake it works real nice when the lower is ported.
There are better intakes out there and the performer 2 sounds like a nice piece but I would say stick with the cobra and see how it works first, you may be happy with the gain from the heads they are very good heads.
You may lose bottom end torque with the newer intake and that is nice in a street car.
Definatly get a new MAF a Pro M might be a better choice then the C&L but I have heard good things about the new C&L 76mm kit but I have no first hand experience.
