Paint exhaust manifolds?
You can put 340s and 360 magnum manifolds on just about any small block mopar. I prefer using the newer heads with the larger exhaust ports that match the 340/360 outlets. But there are quite a few FABO members that have used them on the earlier (late 60s, early 70s) heads.
I'm running the large hole 340 driver's manifold with the 360 magnum passenger's manifold in my '69 318 Barracuda. I used the 302 casting heads to take advantage of the larger exhaust port. Any 360 should also have the larger exhaust ports.
