He had a booth set up at one of the World of Wheels shows, they looked very impressive. I don't remember how much he quoted me, but I about choked, knew right then he would not sell many.

I would love to see these come to life again...If I had won the lottery, I was going to buy a Centroid CNC machine and see if I could re-do them myself.

I remember reading about those. The rocker arms looked cheesy AF. This would be a FAR more worthy effort:

I would love to see a 32valve deal based off an enlarged version of the first coyote heads. They flat work! Not to mention the R&D that could be copied. Olds did something like this way back in 69?. 455 4 valve, made 800 hp at 8000 rpm, back then!!!! Just think what a 550 cube 32 valve could do. Easily over a 1,000 hp. And live!

With today's tech, im shocked there is not many many one off heads and intakes being made. It wasnt hard in the 80s, it should be simple today.

Hyundai's CVVD design may make multi valves less necessary. I think they are onto something that has much more potential.
They've been developing this for 9 years, and it will have the 10 year 100k warranty!

Looks like the same thing multi air does but much more mechanical which would be a big plus over solenoids imo.

MultiAir or Multiair is a hydraulically-actuated variable valve timing and variable valve lift engine technology enabling "cylinder by cylinder, stroke by stroke"[1] control of intake air directly via a gasoline engine's inlet valves. Developed by Fiat Powertrain Technologies, the technology bypasses a primary engine inefficiency: pumping losses caused by restriction of the intake passage by the throttle plate, used to regulate air feeding the cylinders.[2]

Forced induction is probably why we don't see these heads. A 32 valve head for Mopars would be a very small market vs a super charger that is basically universal save for a few brackets. Just not cost effective given other tech on the market that can achieve the desired power levels.

IDK how much time was wasted trying to develop cam profiles, which are really different from 2 valve engines, typically less overlap.

Thats one of Joe Schubecks creations said to have a six inch stroke and 1500hp and 1200 TQ.

There is some info on them via google and I tried to find a vid and there are a few but none with a running, racing version. Id of liked to seen a vid of one getting busy or at least hear what it sounded like.

What the heck did I just watch? Cold start it and instantly rev it to 7500 RPM with his head bouncing all around and blurt out some random number for HP? Was that even a dyno or an engine stand? The engine looks and sounds impressive but the video is really weird to say the least...
