early V8 exhaust manifolds

An old set of 360 exhaust man. would work on a Barracuda. Less restriction than273. Or would a Vaiiant be different ?
I have yet to see a set of any manifolds that will work, just the 273 man's will. Same as Barracuda, if you can show me or point me in a direction that would be cool Pete .

I have some 64 - 66 273 exhaust manifolds.
Hold tight, I am seeing if I can tackle these myself, if I can't I will be getting back to you :thumbsup: Thank you
