The heat sheild was not originally painted at all. I've seen them with traces of original engine paint, but never traces of black paint.
Heat stove that connects to air cleaner tube is black paint dipped.
The exhaust manifold get the majority of paint near the block mating surfaces. So that is way you will see traces of original paint near the exhaust ports because the paint was thicker there.
This is the same motor above but with about hundred miles on it. Notice the overspray went away.
Again, this is not my car. This car was Troy Bray's (ns1rm21 here).
