Hirsch paint is rated the highest temp of all the paints out there. The key, as stated on their site also, is to clean and prep well, and then, on the exhaust ports for the heads and the heat cross over on the manifold, you only spray a dusting of paint, just barely enough to cover, and that's it!

I've had mine on for 3.5 years now and while it is getting that green/silver heat tint, it's still wearing well. It's to the point where I'd like to redo it, but it's all still there.

Also, with a new motor, you will have higher temps to deal with, and if the motor runs lean at all, you can burn these areas faster...

And yes, the basic look should have a satin finish to it, not a true Flat Black for under the hood.
