440 exhaust in Valiant

Hey All.

I am installing a bone stock 78 440 in my 68 valiant.

I need a clear answer. Can I use a factory exhaust manifold? If so Can someone post a picture of one??

I am trying to not have to buy headers this year. I have a pile of stock exhaust manifolds and I'm hoping I can squeeze a set in there.

just trying to get her on the road before I move.

Thanks

68 Valiant
