Orange overspray on SB's

[MosportGreen66]

I would assume that the LT-1 did not have a significant amount of overspray on the intake manifold solely because the valve covers were not painted. I would see a nice overspray line on the intake of a car with a painted orange valve covers like the '65 L-78 or L-72 in our Corvette. But motors like the LT-1, L-79, DZ302 should not have much overspray. The areas like you mentioned, on the front and rear of the intake (north and south ends) but not on the sides.

Great pictures.
