I have uploaded that one as well. I made this symmetrical so I could order 2. I did have to drill and tap inlets & outlets. To make it more bullet proof, you may want to add a groove for a gasket to ensure everything seals well.

I have never had a problem or even remotely close with cooling. This is even with multiple drag runs, multiple auto-x runs, and hot laps in the summer in California.
