I remember seeing a spherical valve engine setup for the 302 that was (in a way) similar to DOHC engines. It used two shafts with these half-sphere shaped chambers instead of valves and springs. I can't remember for the life of me exactly how it worked, but I can remember that it blew my mind to read about it. The whole setup for a 302 was like $20,000 or something. It also used a redesigned block due to the lack of a camshaft.
I've never thought rotary engines were all that and a bag of chips. They've been sold on their efficiency for decades and, while their horsepower-to-size ratio is impressive, they've just never done anything that really wowed me. And like Unit said, they need to turbos to make big power...and thus cutting their lifespan.
Those dominion heads were really impressive (if not enoumously expensive). The four valves made big power up top and the fact that the valves themselves were relatively small allowed for decent low end torque. Not a bad combination if they didn't rip your cam apart in the process.
