So, I need to weld a block to the exhaust manifold. I believe this is 409 stainless steel. Does anyone have any experience or tips for welding mild steel to 409SS?

The exhaust manifold should be cast iron... you can braze to it much easier than welding. Welding will likely leave micro cracks which will enlarge over time and leak.

If you can find a fairly flat spot on the manifold, you can just drill and tap a mount location right into the manifold. Probably best to get a spare, though.
