I purchaced a 406 some time ago and have tore it down and Im changing cams and some other stuff. The original owner claimed it had1.6 rockers but the 1.6 rockers morphed into 1.65s (original owner insits Im wrong but ive measured a number of times)
I have no geometry issues or binding. Piston to valve clearance is at .120 with out gaskets. Measured with a solid lifter (roller) Cam button clearance is .004-.005
My springs will bind @ 650 lift so Im clear there.
As is Ive got .580 on intake .593 exhaust
Here comes the question
By all the info Ive found my heads (TFS 23*) will putter out at .560 intake and .570 exhaust.
So that makes about .020 lift past where the heads stop flowing.
Is this going to be Good, Bad or indifferant.

I remember an Engine masters Small block contestant claiming .858 of lift but I cant remember his reasoning though.
