Kenholton is right. The Aussies got the 302 cleveland, instead of the BOSS 302. Which were pretty similar in performance.

Ask anyone who's been around for awhile building engine's, they'll tell you, if you can find the 302 cleveland heads to buy them if you've got the money. IIRC they're a 342 CI engine.

In 2001, Ford Australia also built some stroked, 5.6 L (5,605 cc, 342 cu in) Windsors with reworked GT40P heads (featuring larger valves), a unique eight trumpet inlet manifold, long throw crank, H beam rods and roller rockers. They produced 335 hp (250 kW) at 5,250 rpm and 369 lb·ft (500 N·m) at 4,250 rpm.[10] The 5.6 litres of displacement was reached by lengthening the stroke from 76.2 mm (3.0 in) to 86.4 mm (3.4 in).

Lots of information here but lots of it wrong.
I'm bring this up just because if someone googled something and found it they might take everything as fact.

Lets start with basics. Measured from the center of the crank to the top of the block where the head bolts on.
Deck height on the 302/5.0 is 8.2" it varies a few thousandths.
Cleveland is 9.2"
351W is 9.5"
351m/400 has the same deck height as a 460, 11.3xx"

2v vs 4v, does in fact refer to the carb, The 4v heads have VERY large ports and are not good for torque but will spin to very high rpm.
2v heads have a smaller port size and make good power over a wide rpm range and make torque.
Then Aussie 2v heads, have a closed combustion chamber for higher compression.

The Cleveland and 351m/400 all suffer an oil issue, the oil ports to the lifters is actually to large and cause oil pressure to vary at the mains due to this, under normal car/truck loads you may never see it, But start cranking up the HP and RPM, you best have the lifter bores bored out and sleeved and the oil issue goes away.
The Cleveland head is also prone to cracking. Finding a pair that isn't cracked can be a challenge today.

So you want to put it in a Truck, your in luck, its just a small block, use 5.0/302 motor mounts even on a 351m/400 just need the correct oil pan setup.
I had an 82 F150 4x4 that came stock with a 400m in it.

Another difference is the main journal size, Cleveland uses a smaller diameter main bearing than a 351W.
