[QUOTE="shurur, post: 16403991, member: 113850"] They were designed for a particular intake design; so I will be looking at that particularly or whether the heads were all tested on the same test-bed. Thanks ⁸8888888888888888888888 The increased midrange torque pro-duction and greater overall area under the power curve (when[b] compared to swirl-port heads[/b]) will enhance the performance of a street/strip modular regardless of application. 888888888888888888888888 Fox Lake's worked B heads flowed [b]nearly as much[/b] as the newest tumble-port heads, relying mainly on sheer volume, as opposed to velocity as in the newer single-intake-runner tumble port casting. 88888888888888888888 I realize that the c heads are not the newest tumble port heads, but I thought that c heads flowed better than all b heads. Maybe it is more about the velocity. This is an old test, 2004. I may toss this up to the nasvt FB page for more clarification. I am just not buying this at this point. Todd Warren, na svt, has said that the c head will make more power na or fi than the b head. Maybe it is a velocity vs flow issue though. [/QUOTE]
