Has anyone seen these 4 valve per cyl heads before?

This company engineered some 4 valve per cyl heads for common v8's and other engines not currently using that technology. They have some flow test and other testing they have done. I just have not seen or heard much from and about themselves. Possibly because the cost of the heads is upwards of $10,000 and more. However reguardless of the cost, i am still inquisitive on the design and true results of them.

Those are the old "Dominion" heads, they've been around for quite awhile (ever since the advent of the LT-5 ZR1). I have an old article from Super Chevy that ran a comparison between those heads, and some AFR's. Alhough the Dominion's proved to be slightly better, when you factor in the cost, they're clearly not worth it (which is why you rarely hear about them). Those who decide to go with these heads, do so simply for bragging rights.
