Flow numbers on Ported Edelbrook Performer Heads

Has anybody been exposed to any flow numbers from ported Edelbrock Performer Heads (1.90" Intake vales)? I'm curious what a good bench mark is for a half decent port job is. I now what they flow stock, but if anybody has taken it upon themselves to port a set of these heads, I'd be curious to see what kind of results they got.[img]/phpBB/images/smiles/icon_confused.gif[/img]

they flow about 220-230 stock. i think fully ported they might flow 250
