Yes, you are essentially correct. In the late sixties, racers put the Cleveland heads on a 302 Windsor block and called it a Clevor. Ford picked up and that, and called it the Boss engine. They added things like 4 bolt mains and screw in freeze plugs.

The process is not overly difficult. Requires drilling some steam and water holes, and a couple of other minor things.

Of course, with cleveland heads, you have to use a custom intake manifold, and special headers to make it all work. The Cleveland heads are also bigger/wider, so there's often a space issue.

Is it worth it? IMO, no, it isn't. There are plenty of off the shelf Windsor heads that will easily outflow the cleveland 4V heads, and perform better on the street than the 2V heads. Why go through all that hassle when you can simply bolt on a pair of Canfield headas?

When done correctly by competent engine builder, a canted valve cleveland head makes a ton of steam, BUT if you are not familiar with a canted valve head, leave well enough alone and pick a head from the summit catalog

what exactly is a canted valve head? like what makes it so?
