96-98 NPI heads

I have done searching all over the place, and of all things what I can't find is a set of flow numbers for the stock 96-98 heads - no p&p job, no PI valves... nothing. Just the way they left the factory. Can anyone provide me with them? I'm trying to compare various different configurations, and I've got most I want except this.

[rant mode] I guess all the stangers skipping over the NPI heads isn't helping, but I find it odd they can't produce flow #s for them... how do they know they're "boat anchors" if there aren't #s out for them? [/rant mode]

96 Mustang GT 5spd. w/ 248A Option (GTS). Stock for now until I get the Roush on.

24k B&M Cooler, 1" lowered, Steeda UD Pulleys, Dynomax cat-back, J-mod, 3.73's, PI intake, PI cams, 03 GT MAF/Tube, SCT tuned - Gone but not forgotten.

Nobody has a clue? There have to be 500,000 pairs of these heads out there from the cars alone... ignoring any of the truck variations. Someone must have a decent idea....

Yes, I've seen a chart, and I think I've even posted it once, but can't seem to find it now.

In summary....Bump.

That's funny, I thought it was the 94-95 blocks that are the anchors.....

With a little help, my 96 NPI's aren't doing to bad...

But, I digress... this is a good question, maybe a more specific title like "'96 - 98 Heads -- flow numbers please?" might elicit some response... I know that someone out there knows the answer, or knows someone that does....

In short:
Bump, again
