Hello All-

I have recieved a small quantity of Australian 351 Cleveland cylinder heads from Australia. In fact, I have 5 sets that I'm trying to sell. They've been cleaned and magnafluxed and are in rebuildable condition. I hate to use this forum as a sales tool, but I've recently been laid off and need to move these out of my garage. I'll sell them for $425 and give you free shipping. If you like to view pictures of a set that I've had cleaned, then click on the following links.









Let me know if I can help,

Chance Dorsey

They are closed chamber 2V Heads

Much better port velocity for that little kick on the low end of the RPM Band.

Heads

From what i understand all australian 351 2V heads are open chamber. All australian 302 2V heads are closed chamber, that would make the heads in your photo 302 heads. Tha ports are the same, just different combustion chambers.

Give that man a cigar.....

.....however, you must consider the fact that anyone using these heads in the U.S. on a Cleveland are in fact using them on a 351 Cleveland in order to boost the compression and take advantage of the quench design and the smaller ports for better torque. There's not many in the U.S. building 302 Clevelands. In the circle of motorheads I run with, these heads (technically 302C heads) are affectionately refered to as Australian 351 Cleveland heads. "Aussie heads" for short.

The 2V and 4V terms don't really apply to Aussie heads. There were no large port heads produced there. They all had small ports and small valves. 351s used open chambers and 302s used closed chambers. There is no 2 or 4 cast into the corners. They also made small port 4V intake manifolds. I'm fairly sure for spread bore 4V carbs only. No holley bolt patterns.

aussie heads

May 19 2002, 7:34 PM 

Brain in the aussie falcons, GTHO's were fitted with 4V closed chamber heads cast in the US. Falcons with 2V heads were fitted with open chambers some were 2 barrel some 4 barrel depending on options etc, the 4 barrel intakes were square bore holley flange in 2V port size, and when the polution motors started to come out ford Australia started to use the spreadbore intakes (can't give them away)with carter thermoquad carbs only during the late 60's early 70's in the GT falcons we were lucky enough to have the 4V's fitted from the factory hope this helps out

I knew all the large port heads were imported from the US. The intake and exhaust manifolds may have come from the US as well.

I wasn't sure about the carb patterns. The only pics I've seen were for a spread bore carb.

'69 was the first year for 351W.
'70 was the first year for Clevelands.

The GT Cleveland engines were rated at 300 HP. I don't think that was realistic after they switched to small port 4V intakes and dropping compression down to 9.5-1.
They just used the old figures.

My best guess is 1972-73 for the last big port heads.

While the Aussie closed chamber heads may have been used on a 302 there, if you look at the water passages in the pictures, you can see that these are desigined for a cleveland block, and will not go on an american 302 with modification (the water passes through the block in a cleveland, through the intake on a 302)

Aussie 302C versus Boss 302

May 21 2002, 4:43 PM 

Right, the Aussie 302C has nothing in common with a Boss 302. The Boss 302 uses a 8.2 deck Windsor block. The Aussie 302C uses a 351C block with a short stroke crank.

If they are 302 2V heads, are they basically a Boss 302 head, and will they bolt right on to a cleveland?

I thought that the 302 heads had a different routing
for the water passage.

More Aussie 302C

May 21 2002, 4:48 PM 

>If they are 302 2V heads, are they basically a Boss 302 head,

No, they are basically a 351C-2V Cleveland head. The only meaningful
difference is the quench chamber design.

>and will they bolt right on to a cleveland?

Yes, they will bolt right up to a Cleveland because the Aussie 302C is
nothing more than a 351C with a short stroke (3") crank and longer rods.
Externally, it's identical to a 351C.

>I thought that the 302 heads had a different routing for the water passage.

Boss 302 heads have the Windsor routing but Aussie 302C have the Cleveland
routing.

302 clev stuff.

May 23 2002, 12:51 AM 

Dan, seeing you know that the 302 clev had longer rods have you ever tried using them in a 351? There is a piston available for this combo and it will give some good results, especially with the 2v heads and dual plane maifold, we made just under 500hp with one such combo.

Long rod motor

May 23 2002, 1:32 AM 

This was a very common practice in Australia. When rebuilding a 302C, many people buy a 351C crank, use their 302 rods and buy custom pistons with a shorter pin height.
An Aussie should be able to point you in the right direction for the parts.

long rod

It adds about AU$100 to the build to go long rod. We always run them.
