Yeah, they're both "A" motors, so what fits one will fit the other. Only difference may be the size of the runners. If you have a mis-match there, you could do some gasket matching. Just be sure to run your cutter far enough down in the runner that the vessel doesn't look like an Anaconda that swallowed a pig in the side view. If you have a large volume like that at the intersection of the manifold/head, the intake charge will slow down there and drop fuel out of suspension. Then it'll be lean/rich/lean/rich/lean/rich as the fuel drops out and then gets picked up again and it'll be a tuning nightmare. Probably the best plan is to bolt it on and forget it.
