Interesting idea... I will be sticking with the 2,0 heads because of the originality issue, and a set of overbored 85mm birals would appear externally the same as the 80mm that are there now. There is another option for an original-appearing cylinder but I don't think that's for public discussion here. So the heads would have to be cut for 2,2 cylinders, and could probably stand being opened up to 36mm while retaining the original valve sizes.
Decisions. . .decisions. This will be a lot easier once the engine is torn down and I can make a true assessment of what I'm dealing with. . . stay tuned. . .
