i don't understand the question. Stock iron 351-C heads are either 2-V (smaller valves & ports) or 4-V (giant valves & ports). There is also an early-'80s SVO-Ford aluminum head called the A-3. Have you found something else you want to run called the 3-V?
Jack,
I am talking about the heads that Pantera International is selling http://www.pim.net/newprod601.htm
They are made in Austrailia I think.

There are a couple some fitment issues to be aware of. First, the exhaust
flange bolt holes are raised by 0.4" inches, enough to cause problems with
the headers I run in both the Pantera and the Mustang. Second, the intake
port is an intermediate port size meant to be used with a raised floor
intake like the Parker Funnelweb or TFC. Neither is an exact fit to the
ports but can be port matched or left alone.
The Australians I've talked to have said the same thing about the 3V heads.
They don't flow near what the manufacturer claims out-of-the-box and require
a lot of porting to reach 320 CFM on the intake. An iron 4V will flow that
with just a good valve job and bowl blending, BTW.
Next month's Popular Hot Rodding magazine is supposed to have an "Engine
Masters Contest". Dave Stoerling built the Ford motor in the contest,
using the 3V heads and made well over 600 HP.

Yes by CHI (Cylinder Head Innovations).

Mike Fielder imports them and attends the Columbus Ohio All Ford swap
meet and I think the PRI show.
