340 vs 360 confirmation

Would I be correct in assuming that any of the stock exhaust manifolds for an early 70s 340 will flow better than the mid 70s and late 70s 360 stock manifolds? I have a chance to pick up some 72 to 73 340 manifolds dirt cheap.

Since I'm building a daily driver I'm going to ditch these awful headers. I'm not saying all headers are awful, but the ones I currently own definitely are!

Thanks again folks.

The 72-73 340 manifolds will work just fine, but make sure the drivers side is for an A body. Passenger side is the same between A, B and E bodies, but the drivers side is specific for A body cars. The only difference between a 68-70 drivers side 340 HP manifold and a 72-76 340/360 drivers side manifold is the later ones have bolt bosses cast in to hold the heat stove that the heat tube going up to the air cleaner hooks to.
