What are the best Cleveland heads?
By far the best factory 351C head is the Ford Australia 4V casting, which has the sweet combination of the 351C-4V wedge chamber with the smaller 2V ports for great low- to midrange torque. It remains the best factory head ever produced by Ford for this mill.
Are 2V or 4V heads better?
The biggest physical difference between the 2V and 4V Cleveland heads is the huge intake and exhaust ports on the 4V heads. There simply isn’t enough material around the smaller 2V ports to hog them out to mate to 4V port dimensions.

Putting Windsor heads on a Cleveland engine is possible, but you will need a custom intake manifold. Putting 351C heads on a 351W also requires a special but available intake manifold. The 351C 2V heads with canted valves flow very well and produce good power.
Which is better 351W or 351C?
“The 351W is a basic 302-type engine. The 351C engine got all the hype, but what we race today is the basic W or a combination of the two. The W is a better engine for long-lived low RPM power. It needs proper preparation to race, and, as it has the better torque curve on the low end, it is not a high rpm engine.

What is the compression ratio for 93 octane with aluminum heads?
Because aluminum conducts (dissipates to the cooling system) heat much faster than cast iron does, you can run 10.5:1 with aluminum heads on 93 octane. For those running 87 octane, 8.7:1 is the most that is safe with cast iron heads, 9.7 with aluminum.
What is the advantage of having aluminum heads?
Aluminum heads will dissipate heat faster. This allows for higher Compression Ratios with less risk of Detonation. The cooler head also delivers a cooler air/fuel mixture to the combustion chamber. Cooler air is denser and can make more power.

Which is better 351 Cleveland or 351 Windsor?
The Windsor has the better parts availability and support going for it. If you’re gonna build one with plenty of aftermarket parts, then the Windsor is the clear choice to make. However, when it comes “stock vs. stock”, the Cleveland will walk all over the Windsor because it has the ability to breate, as to where the Windsor’s stock heads are
