Cleveland VS Windsor
I am in no way arguing with any of the above comments. They all have merit, in different ways, for different engine builds.
What you consider a "street able" engine may greatly differ from the next guy. When I was younger or as a weekend ride...I can tolerate a much more radical engine than one that I need to depend on daily, for commuting to and from work or the occasional 20-30 mile trip to a customer site during the work day.
I'm a car guy...if it burns fossil fuel and can get out of its own way...I'll drive it (or break it) . But there are some cars in my garage that are not my first choice for slippery roads, long trips or going to meet the in-laws.
I can't argue the point, that given correct circumstances, a Cleveland style head will generally out perform, produce more horsepower than comparable wedge (usually!), but that doesn't always make it the best choice. Just like Mopar found out, the old wedge headed FE's were known to spank even Hemi's in the right conditions, with the right tune.
When building an engine you need to look at the whole package, How much do you want to spend, what is the engine expected to do, what is its expected operating range (3K - 8K, 1500 to 6K), are you going EFI or not, how much fabrication are you willing to do to make th engine work in the chassis you are using?
Also, the cylinder spacing for the W vs C engine is the same, otherwise the heads (combustion chambers) wouldn't fit, they would be in the wrong position. There is a lot more similarity between the C and W engines that you would think. Ford has never been one to reinvent the wheel, when it isn't needed. As a personal opinion...that's why so many ford guys resist change. The Mod motors have been on the performance scene for 10 years, and they are just now being readily accepted, by the 5.0 crowd, as worth building. Same thing when they changed the design of the F-150. Ford guys are a stubborn lot!
The same thing happened when the 429-460 replaced the 428-427, the resistance was so great that Ford had to sell both engines as an option in the Fairlane / Torino 'cause a lot of guys didn't want to take a chance with the "new" motor, no matter how good it sounded on paper. The flat-head guys?...well, they will never change. The world is flat, and that's that.
