A fair amount of work to achieve this I would imagine. Moving the inlet port up and re shaping and an insert to plug the original track.

Are the HP gains worth the effort?

Is it designed so the inlet port runs down to valves instead of being flat? Is that the concept?
The Weslake Xflow head inlets run down to the valve.

What do you think? I can't read Japanese so have no idea on what the page is about.
