Okay as far as technical details I'll throw a few of my ideas out for your consideration.

Number 1 I'd go with an 8BA design. I'd eliminate the removable valve guide altogether. If cast in aluminum (which is the right thing to do, who would not want to shed over 100 unproductive pounds?) I'd look strongly at "PTAW" for better quality, ease of manufacture, and even lighter weight. This is Plasma Transfer Arc Welding. It is an a amazing technology. It can be involved in moderately high volumes of production. Its cost effective compared to and probably ALOT less problematic as it is to fit a traditional dry sleeve in an aluminum bore.

As a side note a PTAW bore will run cooler since there is no joint between the liner and the cylinder itself.
