well if money is not an issue then I would go with Todas, they make good power from midrange all the way up top, but they won't make any power unless you're bumping atleast 12:1. My spec B's required a minimum of 11:1 to extract any power which still wasn't enough.

Skunk2 pro's are a good choice also but still need compression to compensate for them. The supertech HD kit can handle just about any cam on the market and is a pretty decent price at around $400 for the whole setup.

Why not change the b16 block out for a b18/b20? more displacement will help.
