I don't mean to hijack this thread, but since you asked... Perhaps you can reshape the baffle so that your intake will clear. Cut, section, weld...it would be worth the effort if it can be done. Otherwise perhaps you could fabricate a baffle which fits in the same place and performs the same function, but which is more compact. The air cleaners should be irrelevant. The vacuum source is from beneath the carburetor butterflies, not from the air cleaner. The air cleaners are not involved in a PCV system, other than in some factory systems where the air cleaner is used as a filtered fresh air intake source for the crankcase. Hope this helps.
