Not trying to hijack someone's thread but since we have a good Clevor discussion going on here, I thought I should post some of my 302 Clevor pictures. Maybe get some creative juices flowing.
As for the common reply...

What do you guys think the Cleveland are? Ford designed them as full race heads to begin with. Even today, the design is still good. Take a look at the Engine Masters Challenge. The Cleveland headed engines have dominated for years. I know these heads don't have as nice of a quench chamber or flow as well as a set of store bought AFR or Trick Flow heads, but I don't care. My engine looks cooler. 
Plus, being an engine machinist/builder by trade, it is the best way for me to stand apart from the competition who just bolt stuff together.

no point except to be "different" now days..
aftermarket heads are cheaper in the long run and much better..

There are many aftermarket heads available for the 351W that work better than the old Cleveland heads, and will use more standard 351W intake manifolds.
If you just got to be different and you have some actual cleveland(not modified) heads kicking around then sure have at it, but if not then you can get more performance for less $$ using standard windsor parts now.

Need vs want
C heads shine at high rpms. Kind of a waste for a cruiser/5 speed. Im currently building a C engine and gave some good consideration on using W heads. With a 5 speed I dont really need canted valves. W heads would have been different, but in the end I wanted canted valves.

I always wonder why some many people claim you need small ports to make torque. One of the highest torque gas engines Ford ever made was the 400. I wonder what heads they used?

I also think you should use the old term for these engines: Bogus Boss. Clevor really only applies to a Cleveland headed 351W block

It's more like 'Down Right Sexy"
As for what to call it, I usually just say it's a boss 302. The only noticeable differences (like the rear sump pan, and 50 oz balancer) take a keen eye to distinguish. My understanding is that most 302's (not the famed Mexican ones) were cast and built in the Cleveland engine plant. Maybe I should call it a 302C.

Don't 302's have an 8.2 inch deck?
I'm likin' it, blueoval!!
I've never been a believer in the "Clevelands are only good for high RPM's" school of thought that seems so prevalent. Every one I've ever worked with has been just fine at low RPM's, with that great top-end rush just waiting to happen.

Ditto here. My brother had a 71 Torino GT with the 4 bbl quench headed 351, it was no slouch off the line even with the automatic transmission and 3.00 rear. Got a ride in a 70 Boss once, it too was anything but sluggish. I think the bad reps came from those who insisted on running the 4 bbl heads with a single plane intake and a carb that was too big. (ala SBC style)

A set of well built canted valve heads brings back such fond memories of the Boss 302. I've lusted after them since I first saw them some 40 years ago. The only thing that might make them sexier would be a great set of valve covers:

Just picked up a f4te W block so want to tear it down and drop it off at the machine shop. And am also VERY ready to get some boss pistons and some cast iron aussies, and shoehorn it into my 65 merc. But the cleveland is not done yet for the truck

Another High jacker in the house,
@blueovalandy, I believe we must be brothers from another mother or something... basicly I see the same build up. There are several different ways of building a clevor, but i believe they are all good and on top of it all a real challenge.
I took the liberty to make a blog about my build and the Mustangs it fits in.
Also, I made some cool clevor decals for this engine.
Soon, begin next year I will launch a video from the new engine and if you want i share this.
I use the 302C heads and makes 343 HP at 5400 RPM whats not bad for a 302 with cast iron heads
