Default 502 replacement manifolds

What is the best "bang for the buck" when replacing 502 manifolds. Would like to get the entire kit needed to replace the stock manifolds with performance ones. Looking for recommendations.

Considering recent threads on aftermarket exhaust manifold performance gains, I would look at Revolution Marine as the best bang for the Buck
