Will 67-69 dart stock small block exhaust manifolds fit on a late 70s-80s 318 in my 72 duster?

KBharley,
I own a 69 barracuda it came with a 318 with stock exhaust. I put some 302 casting heads on it (late 80s -early 90s). Many of the 80s/90s heads have a smog port just under the exhaust port. I can post a pic if you like. Anyway the old manifolds won't cover the smog port so you have to plug this port or you'll have a leak. I also switched to Magnum truck manifold on the passenger side ('91-'92). These manifolds are available on Ebay for about $60. The truck manifolds cover the smog port and also give you much better exhaust. The exhaust port on the manifold is about 2 1/2" where the stocker is about 1 3/4 if I remember correctly.
I have posted pics of the truck manifolds on my Cuda on the thread

I also can post pics of an extra set of truck manifolds I still have so you can see the smog ports.
Hope this helps.
