Those will be fine. I'd like to think you placed an anti-seize compound on all of your threaded and clamped connections.... Regardless, those Gr8 will be fine.
I am hard pressed to think a riser gasket could solve or could have created the problem. However if it does fix the problem, good for you. Those gaskets don't look bad. I have seen worse, by far. What stinks are the paper gaskets that have become available. Used to, one could find some much sturdier gaskets made from a graphite material.
If not, I'd go back and do a mag-particle test on the exhaust manifold. A visual inspection for cracks can often be insufficient. A MT is very simple to do if you look for someone that has the test equipment. Most engine shops or machine shops should have the equipment. Easy and inexpensive. However, your area for testing will be limited without pulling the manifolds. A small crack that takes a MT for inspection should not be big enough to allow the type of water intrusion that you have described.
