I think Inwas told the lower head uses Maserati type PI injectors to spay the fuel on the back of the valves,

Tony Lindsay-Dean is building an engine using that type of head.

Why? No power benefit to this.  OEMs do it for emissions, especially during warm up.  Best power comes from injecting further back as fuel vaporises more fully.

Top pic is interesting Marcus,  likely prototype as you say.  Never seen that pic before - thanks for posting ☺️
