Our exhaust header has seen some better days. It is pretty rusted and has a lot of carbon buildup, and also the flange is kind of jagged. I was wondering if we could port it a little or at least clean up the jagged parts. I figure sand-blasting it is perfectly fine, but can we get it ceramic coated?

Rules explicitly state no painting or coating, so no, not legal.
It’s become accepted practice to paint the engine and rocker-arm cover. We probably ought to submit a rule change to clarify that.

That’s fine, clean and blast away.
Don’t be tempted to blast your intake manifold tho. No matter how much you clean it afterwards, grit will find a way into your cylinders.
