With the stock cast iron calipers, should they be left raw? Maybe use the same product that is used on the cast iron manifolds?

I was thinking that if you paint or powder coat the cast iron it will hold in the heat longer.

any thoughts

Clean them up really well and paint with VHT caliper paint. Available at most parts stores. The calipers were painted black from the factory.

Caliper paint will work. And it will also be damaged from brake fluid. Powder coating holds up to brake fluid. Just my experience.

What about the heat being held in the casting by the coated surface

I don't think the paint will make an appreciable difference to heat dissipation, but I could be wrong... I used black caliper paint on mine too.

It's not going to be an issue. Are you racing the car?

A friend of mine paints his air cooled Vintage Honda racing engines and has no problem......this may help you with the heat question.
He ran them naked prior to, with no discernable difference in temperature.

When I re did my brakes this last time, I sent the calipers to VB&P for new pistons and O rings, and while they had them I opted for powder coating. I was surprised how nice they looked when I got them back.
The calipers were already SS sleeved, so the rebuild was pretty inexpensive.

I used silver Dupli color brake caliper paint on my 78 10 years ago and they look perfect today...use brake caliper paint, NOT high temp paint.

Flat paint dissipates heat better than gloss paint does, however I suspect the majority of heat is dissipated by the rotor.

Yes, but just for fun. willow springs. May even try a autocross

I read that coating cast iron holds the heat in, aluminum is a different animal.

Others have already stated coating or painting is not an issue. I also have VBP powder coated calipers, I really doubt a reputable brake vendor would do anything to compromise their product. If you are still concerned, leave them bare. Surface corrosion won't hurt anything.

Aluminum disapates heat 7 times the rate of cast iron so there may be some validity to this....but I would bet it is marginal.

thank you, that is what I was getting at. I just don't know if it make a noticeable difference

Is that pink?

It depends if you can see them through your rims.

Had mine locally Powdercoated. No problem with overheating yet. Although they brake better than before now due to the new O-ring seal type. I used to have the lip seals.
BTW as seen in second picture, They are liquid cooled!!
