yes on the intake, thermoquad manifold,’71
On my '70 exhaust manifolds, the center port is divided. Not sure about the post '70's though.
I can't find anything on these numbers on the exhaust
The 953 manifold is 273/318. 1967-72 ABC
The other one is probably 73-up

Found this on the exhost....
I assume the 6 referenced is what looks like a 3 or an 8 in your photo.
4006741 exhaust manifold.
4006741 is a 72-74 318 a-body left/driver side manifold, should fit your 70 Duster but the price sounds kind of high to me for a 318 exhaust manifold, maybe if they were both 360 ones, would be nice to have a matched set on a 340
