Yep. From an old CC catalog:

"...deep fin design projects a powerful profile...thick alloy to dampen valve noise...external and internal fins provide maximum cooling...polished fin edges accent gloss black...o-rings...1) won't leak 2) metal to metal contact provides heat transfer and cooler head temperature...vital on today's hotter running, emission controlled engines. $179.95 pair"

All of it makes perfect sense...until the part about dropping head temps. I'd need to see two thermometers on one bike - one head with the Cool Cover and the other w/ a stock cover - before I'd believe that head temps are dropped in any meaningful way. There's already a lot of fin surface area in the hottest part of the head. But I'm a skeptic.
