Yes, i've seen these before. Very exciting, i believe the eighth port is a shared port though?
Great that it was produced with the 998cc block in mind also!

There are some great videos on youtube showing blocks being machined from a solid lump of ally on a CNC, absolutely amazing and facinating to watch.

It is a beautiful piece of work, but has (in my opinion) been compromised by the siamesed exhaust port, this makes in in my book a 7 port head, not a true 8 port.
Still, if I had designed it I would be very proud indeed.

isn't this the compromise of any 7 port that's trying to use a std five port cam?
the positions of the exhaust ports cannot be moved due to pesky things like head studs and push rod holes.
it does make you think that with all the skill and thought that's gone into this exercise it would have been so much better of he had started with a proper 8 port cam, its not as if he is offering a second saving by the use of a std five port exhaust manifold
