Doug,

I checked it out, that is the Redline manifold those carbs are sitting on top of. If you look at the pics in the auction, it is easy to see the adapters between the manifold & carbs, which is what raises the carbs so much, and why I sold my Redline manifold.

Here's a direct link to the auction:

There's a couple of Pantera owners bidding on the set-up. This would be a good street set up for somebody who doesn't mind the carbs sticking up above the engine screen. Much better carbs for the street than the 48 IDA carbs.

I don't argue that the IDF's aren't better street carbs then the IDA. Not at all.
The ports appear to be for 2v heads. I find that contradictory.
The 2v head is not a good head to use for any kind of a performance application.
While the intake ports can be helped with a "race type" porting job, the exhausts cannot.
Everything is wrong with them.
The roofs are lowered from the 4'v as are the floors.
Line of sight into the valves is virtually non-existant.
They are exactly what they were designed to be, a 3,500 rpm head.
Why does anyone need a 2400 cfm induction system on a intake that flows 200cfm and an exhaust that flows 80?
You are dead wrong about the 2V head. The out of the box exhaust port of the 2V head, even with the smaller valve, flows the same as the out of the box exhaust port of the 4V head. The intake port is the bottleneck, it just doesn't flow beyond 0.550" intake valve lift. Its easy to make 450 bhp with the 2V head, the best port jobs achieve 500 bhp. And a few guys are making 530 - 550 bhp with 2V heads. Then there are the alloy 2V heads that don't have the limitations of the cast iron 2V heads, they are capable of supporting over 600 bhp. The fact the iron 2V heads must be ported in order to support the big bhp numbers is in no way a reason to criticize them. The cast iron 4V heads hit a plateau in power production around 400 bhp and won't make more power unless they are ported. In the case of the 4V head, it's the exhaust port that is the bottleneck, and receives the majority of the grinding work in order to get the head to support more bhp.

A set of AFD or CHI alloy 2V heads combined with this intake set up would make a sweet running combination.

No appologies necessary. The 351-c aussie heads need the perverbial $5000 port job. You can't do $5000 worth of porting on them because the don't have enoough metal to remove.
At best they will flow what a ported 289 head does. Why downgrade?
Even if you were able to port them to where they should be you would just wind up with a good A3 head. Why not start there to begin with and spend your spare time in the hot tub playing with, ah I mean nibbling on Buttered Up Nipples, ah drinking, yup that's it, drinking Buttery Nipples? (:
