Pantera International Motorsport is showing a new 351C aluminum
cylinder head on their web site:
they're clalling the head a 3V due to it's ports being something
between a 2V and a 4V. The head is made by the same Australian
manufacturer that makes the Vapours intake manifold that PIM
imports. I believe that company is Active:

He's the guy that imports the cross-flow EFI intake for
the Cleveland. I believe the intake is made by Active:

Active manifolds+components
363 Victoria Road
Rydalmere NSW 2116
ph [02]98980788

but I've not verified that. The also make a very nice cross flow
EFI intake for the Cleveland.

The port size is matched to the Vapours intake and is somewhere
between a 2V and a 4V. You'd need to port the head to match a 4V
intake manifold port or port a 2V intake to match the head size.
It's not clear how well it will match high port (A3/B351/C302) type
intakes. Perhaps I can get them to send me an outline of the ports
and bolt holes and I can check it against my intake collection?
The guy at PIM said the exhaust port is raised 1/4" and will
accept a 4V header. They sure look like they are raised more
than that to me but, on second thought, it may be an optical
illusion since the port floor doesn't drop like a 4V. On my
Pantera and on my Mustang, for that matter, even a 1/4" would
mean some header and pipe re-work.

I asked a couple of other questions about valve length etc.
but the guy I spoke to at PIM wasn't sure since they've only
just received their first head. I need to contact Mike Fielder
and see if he's bringing one to the Columbus all-Ford swap over

those ports look like they are raised a bunch. Maybe the top edge is only 1/4" higher

On something like a Boss 302 Maverick 1/4" might as well be a foot for header fit.

You see what that company is charging for BARE 351C closed chamber heads and Aussie heads?!?!?!

$650 for the 4V heads and $799 for the Aussies!

You can buy either one all day long for less than half that at swap meets!

Hmmm... I wonder if those heads can be purchased significantly cheaper?

Good Luck!

The Active intake I have, has the standard 2v port size. It was also offered in the standard 4v port size. Unless there is another intake that they are selling on that site, something will need ported to match even using the Active intake.

The aussie 2V 302 (closed chamber) heads are a dime a dozen over here. (I have a set doing nothing in my gararge) If only I had a matter transfer machine... I could get them to the US for nothing, sell them for $200 a pair, and make a fortune!
