Quien Sabe?  But did you see the article in VW & Porsche (before it became
EC) about the guy who built a 4-cyl 911 engine by cutting one cyl off the
end of each of two engines, then joining the singletons to form a four?

Wonder if such a scheme would work with heads...?  And if so, could one
build a head for a UR-Q from '83 GTI heads thataway...?
