But I guess in the absense of anything better, the JS manifold may still be worth considering, given that it's still a good gain over the standard one?

The only other way is making a good manifold your self.
The primaries want to match the ID of the exhaust ports and be as close to 30" long as possible before the collectors. The bends need be smooth and mandrel formed. The collectors need to be 1 over 2 and correctly welded so as not to impede gas flow. The secondaries need to be around 2" ID and be approximately half the length of the primaries. These then need to collect into a 2 1/2 free flowing system.
It's possible to build up a much better set of manifolds than the JS version.
