Obviously 50mm mains cranks cannot be used in A7 or A8

Yeah 50mm mains for Type-S, A4 and A5 5th gens as well as all 4th gens.
None of the H22s got 55mm mains until the A8 and A7. The one thing I don't know for sure is whether or not the last of line H22a S-Spec (Type S) engines got updated with 55mm mains. My bet is that they didn't.
