Early A exhaust manifold questions

The OP 's last piece mentioned here sanity for maybe wanting a small block instead of slant!!!! Sorry , not trying to derail the thought process here!! SORRY!!! all
No problem. Yep, a v8 swap isn't too hard except for the exhaust and exhaust isn't a big issue unless your engine needs more. Stock manifolds, 340 manifolds, shorty headers, long tubes, fenderwells? That is the question.
