273 with 340 exhaust manifolds

Treblig said
There have been a few early A owners who have installed a 60s 340 driver's manifold paired with a 360 magnum manifold on the passenger's side. I sell these manifold sets to FABO members, been doing it for years. I also sell the 70's 340 manifold paired with a 360 magnum passenger's manifold for use on 67 and up A bodies.

I am installing a ATK 360 engine in my ‘65 Barracuda which now has the 273 commando engine. Would you suggest to put a 60’s drivers side manifold and a 360 magnum passenger side on that set up? Will my stock Formula S exhaust pipe bolt up to them? What’s your cost for the pair?
