318 build

Sure 360 heads will probably work but the op didn't provide much more information on his build. There's no mention of intended use of his vehicle, no carburetor or intake manifold choices, is he using headers or stock exhaust manifolds, ignition system, so I went by what little information that the op listed
I notice that too, doesn't mean can't give some basic info on his question until/if he supply's more information. I've ask the OP to for further information too, doesn't seem to be coming so it's probably a best guess scenario.
