Kelford makes a killer cam for VVL that was designed by Mazworx. Mazworx has stated they have a car that holds a nice steady idle on a high lobe with killer cams.
Its because of threads like this that terrible information spreads around.

Coming from the guy that thinks he can run N1 cams on a stock DET bottomend, yet has no clue that P11 cams are the highest lift/duration cams you can run without valve reliefs.
Port size, valve job, valve size, shrouded vs unshrouded, valve lift, stem size, etc, etc all play a major role in how well a head flows, not just port size, nor valve lift. The exhaust port on the VE is exactly the same size as the DET's, what goes in must come out. Your point is mute.
VE heads do not flow nearly double at the same lift either, I have personally flow benched my head. At .450 of lift, they(VE heads) flow 70cfm more on the intake and 82cfm more on the exhaust than an S13 high port head, which if you know anything about SR heads, is the best flowing of the two DET/DE designs. If you think that a VE flows nearly 400cfm from the factory(which would be double of a highport head) you're fucking high. They do flow a lot more CFM's but double is an over statement.
If anyone is spewing shit into the atmosphere, it's your mouth.
