I think a good o-ring #428 ought to deal with anything even a hot Zs190 swap, we talking at the farthest end possible 212cc, you just dont need a 520 for that. Not enough weight or HP / Torque stress to need a 520, but you can put what ever makes you happy on there, but I think anything over #428 is going to cause as many issues as it solves , especially on the front sprocket case clearance .
