painting 69 mustang 302 engine to factory detail. help?

[ronstang94]

69 Mustang coupe 302, 3 speed manual

I have painted the Block, heads, intake manifold, timing cover, valve covers, and oil pan dark ford corporate blue.

Now the question is-
For a factory finish look, should I paint the bolts and freeze plugs or leave them bare? What bolts do i paint? which ones do I leave bare?

Thank you

the engine was painted as an assembly. i'm generalizing, but about the only items that didn't get some blue were the pulleys, carb and probably the distributor. the exhaust manifolds, water bypass hose/clamps and i believe in many cases the bellhousing had some blue overspray.
