A460 Flow Numbers?

What are the flow #'s on a set of TFS A460 heads?

Gonna have to be a lot more specific than that, there are a bunch of variations of the heads as produced and porting, valve sizing... can change them drastically.

These are the heads I am looking into getting just wondering what kinda flow #'s I could get at around .800 lift?

That's the cnc ported heads...my catalog says 453 cfm @ .800.

What's the biggest recommended lift on these heads? .850 -.900?

The link clearly states that the springs are good for .850" max lift.

Sorry, must of over read that piece.
