Wow exhaust ports on both sides of the head? That is pretty crazy

I would like to see the head casting.

I would like to see the head casting.

agree. My little head was trying to wrap itself around how it would look and work

That's a Lancia Triflux designed for the never-raced Group B rally car, Lancia ECV II.

Pretty cool motor, wonder what the real world drawbacks are of that design?

You can see a little of the head design in the first drawing. The criss-cross valve configuration is interesting. I don't know if I'd see the benefits of twins with today's turbo technology though. It would definitely make a cool RWD project engine though.
