Early A exhaust manifold questions

Rainy Day Auto said
1. Will 67+ 318 or even 360 exhaust manifolds fit and work in an early A (65 valiant)??

2. What's the difference between 273 "super commando" and regular 273 exhaust manifolds?

3. Would any other car line exhaust manifolds fit an early A car (65 valiant), example, I have a pair of 318 ex. Manifolds from a 68 coronet. Would they fit the 65 valiant?

Any other facts and info on early A v8 exhaust manifolds?

You can use a 1973 340 manifold on the driver side, 2.25 exit size and a 96/97/98 Jeep Grand Cherokee passenger 2 1/8 exit on the passenger in an Early A Body without power steering. Auto or four speed. This is an upgrade over the 273 and 318 stockers. If you go this route you need to move the oil filter adapter towards the front.
