Slightly strange head flow question.

Thanks 1wild - Now I get it - I can see now how peak flow well above valve lift won't mean anything to the engine.

So in my combo - I need to keep a close eye on the flow values upt to .550, but above that is irrelevant...yes?

Thanks to all - I suspect my question was a little more "basic" than some of the clued in guys on here expected. :)
