Anyone tried to polish an L/A timing cover?

On my 416 build im thinking turquoise block. Heads are going to be aluminum. V/Cs are polished aluminum. I was thinking a polished timing cover would look nice as well. Anyone done one or have picks of one done? Intake is an air gap and I am going to use a chrome Air breather with 340 pie tin. Maybe ill get it together and decide its to shiny. Im used to stock, everything painted with black wrinkle breather on my 69 Swinger.
