Painting the enigine?

[2kx2]

What types of paints can you use on an engine block. I know of the high temp engine paints but they don't come in very wide variety of colors.

I have seen show cars with the engine painted the same color as the exterior. Is this simply regular automotive paint? Wouldn't the shine cook off from the engine temps?

Someone please help me with this delima. I would really like to do a paint match for the engine block and heads but don't know what types of paint to use.

Thanks
