Headers for 67 barracuda 318 with no modifications

Yes.

And no one was arguing what was better spent money, headers or converter.

The OP never mentioned anything about a converter.
So yur good with helping the newbe spend a lot of money, which is hard to come by these days, on something he doesn't need, but offer no alternative.
And besides that, OP already approved my answer.

Remind me never to call you "friend".........
