You have seen correctly, both the right and left banks have sleeves, 7075 aluminum to avoid permanent deformation on the 2 most stressed banks. The length of the coupling between cylinder and cylinder seat is only 9 mm, I could not increase it, the cylinders inclined 40 degrees touch the central cylinder.Foketry:
It looks like the casting for the top half of the crankcase cleaned up fairly well when you machined it. There's a couple of spots that look a little iffy, but some JB Weld would fix them right up. In that last photo, it almost looks like the right-hand bank of cylinders has sleeves in it, or are my eyes playing tricks on me?
Furthermore the cylinders are fixed to the engine block by means of a separate flange and a retaining ring, a not very stable solution, but to assemble the water jacket inserted from underneath I have not found a better solution .
