Intake manifold bolts
Morning
1968 C3 Intake manifold bolts. Were they installed before or after engine paint ? Should they be free of paint or painted engine color ?
and is correct finish blk oxide or bright ?
Thanks in advance

I agree with PJO, however, generally speaking: if it's a cast iron intake, it was fully painted along with the bolts. Aluminum intakes were installed but the intake was roughly masked/shielded from getting painted but the very lower portion where they bolt to the heads received overspray and the adjacent bolts faces on the head sided show overspray as well.

Sorry,
Car is a 327/350....Survivor
Also, how were different fuel options acommodated (2x4 trips or whatever else was available. Each option would require a different manifold right?
BTW it is a cast iron manifold

Engine and manifold are painted as one. All 68 small block engines were single 4 barrel carburetor. Only 427 had 4 barrel carb and optional 3 2 barrel carbs or knows as tri-power.

Here are two links to the process from John Hinckley, who unfortunately passed away a few years ago. He was a plant manager at the Corvette plant and is considered an expert in so many areas of Corvettes and Chevrolet in general.
