Don' recall seeing it done. IMHO - Getting a true AF05 bore is worth the $. Spree 48mm would forward for displacement, but steps back from stock Aero for port size and timing.

Physical Diffs beyond the exhaust pipe is height from crankcase deck to head (need a spacer) and Spree bolt spacing is slightly narrower (egg shape the cyl fin holes would fix...). Also note cooling fin size difference + AF05 has one more fin.

Which base gasket would you use? I'm sure this would not work properly.
