I will have the flow sheets scanned before the end of the week.

This is a production 6.1 head with our own valve job, portwork and camshaft. The 2.08 valve outflowed a 2.100 Manley Valve by several CFM across the curve. It's a shame we are only running a .577 lift cam. If I could get a .650 lift solid roller into it, point more compression and an adjustable rocker this thing would make stooopid power.
