Looks like the most revolutionary heads for the Windsor engines, practically makes them a hemi instead of a wedge, uses std intake & exhaust accessories, and doesn't require fly-cut pistons.
Of course a boat can't use the cams they used in testing, but makes one wonder what a smartly built engine could do, especially a 396 stroker that can utilize the cfm available.
cool beans, no?

The "new" Clevor engine! Or, the "new" Boss Engine!

Yeah!
Junkyard rollercam 351 + $2500 = Boss 351!
If one were going for authenticity, a rollercam 302 + 289 rods and Boss 302 pistons and these heads gets one pretty close to a Boss 302. Plus the exhaust options for boat or car is way better than for the Cleveland heads.
Only hitch could be interferrence with the valve covers and the riser manifold; log-style would be no problem.

The advertised chamber is 60cc....if your current heads are 54 (can't remember) then you'll lose compression and possibly see very little gains.

Uhm, well ... there is more to power than compression... like an extra 100 cfm of intake flow.

...and you can always mill them down a bit and use a thinner head gasket. And then do not forget to take a bit off the intake manifold.
Oh, with a bit lower compression, I suppose you could advance the timing a bit without worry of pre-ignition which would probably make up for the lower compression.
