Question 351 Cleveland Heads 2v, 4v, Aussie 2v

[Zeke]

I have a chance to grab a set of Aussie 2vs for the stude. I know they have the port and valve size of the US 2V Heads and the quench chamber of the 4V heads.

The question is as manifolds and headers go what fits them? I'd assume that the 2v head intake manifolds fit but what about headers. Do I need to look for 2v gaskets when I build my header?

I'm 90% sure all the normal 2v stuff will work. I think the only difference between the Ausies and the normal ones is the chamber. Brad

correct all US 2V stuff will work. Shawn

Good score! http://www.jalopyjournal.com/ubbthreads/images/graemlins/cool.gif

The 2v heads actually work better on the street than 4v heads do, and four barrel aftermarket intakes for 2v heads were commonly available from several different makers, such as Edelbrock, Offy and Weiand.

The 4v chamber makes the Aussie head the "hot set-up" for street Clevelands, and headers are the same as other 351c or 351/400m engines. Should make a strong running combo for ya!

You've got all the right info - 2V stuff works all 'round.

There used to be a company called B&A that made intakes to put 2V Cleveland heads on 302s & 351 - street boss & track boss. Aussie heads were the hot ticket - they seem to be easier to find now - back when I was really into muscle Fords, they were like rocking horse shit...

Nice score!

They have the "quench" small combustion chambers, which yields a high compression ratio, but have the smaller 2V ports. This combination gives lots of torque over a wide range. I've hear that they can be use to gain upward of 500hp with the right build up.
