You may want to provide the year. Not sure if year makes a difference for correctness however someone will know.

No, not all. Flint shipped and painted what amounted to long block assemblies. Everything on the engine at that time would have been painted orange (and later, blue).

Items installed at St. Louis/Bowling Green were likely to have been unpainted or various shades of semi-flat black. Some fasteners were unpainted.

The assembly manual has pages of diagrams of the items installed at the assembly plant.

You can also use Google > Images and refine your search until the pics begin to show up.

Hi PBC,
If your engine had an aluminum intake manifold originally the manifold and it's bolts might just display a hint of engine orange…. since a 'mask' was used to protect it.
On 4 speed small block engines the bell housing was in place so there's often some orange paint on the housing and the bolts that mount it.
Also the exhaust manifolds were not installed until the engine arrived at St.Louis so the manifolds and their fasteners wouldn't typically have paint on them.
A guide to what was painted or not is to realize there was no engine orange (probably?!?) in St.Louis, so anything that was put on the engine at the assembly plant wasn't painted orange.
Regards,
Alan

I clean and repaint all my bolts, I like to highlight for instance black bolts on a orange timing cover. I don't duplicate factory overspray either.

Probably not factory correct, but this is how I painted my 73.
I think it makes it look neat and I like it. If not for judging,
just do as you want it to look.

Hi PBC,
Here's a picture of a bb being painted at Tonawanda.
I believe people say the worker had less than 20 seconds to paint the engine.
Regards,
Alan

Thanks to John Z.

That's a great picture, EPA not around or in its infant staged. Should have stayed that way!

If are really going for original, you might want to get a copy of the NCRS judging guide for your car.

Thanks Donnie pictures look great, I am not going for factory spec so may like you paint the bolts black as this looks really good. What paint did you use for the gloss black painted parts they perfect.

Thanks for the compliment Paul. I used POR-15 engine enamel on the
engine. For the brackets, power steering pump, and other parts that I painted black, I used
Rust-Oleum Gloss Black enamel. Since I had it apart, I was able to
paint the individual pieces with the spray and if I needed to touch up
the nuts or bolts after reinstall, I used an artist brush and Gloss Black Rust-Oleum
in the can.

Looks real nice and I always like the contrasting colors showing up all the details. Nice!

For what it is worth:

When painting bolts....from what I have found and experienced. The LESS paint I can use the better. Excessive paint film thickness will often times crack away when the bolt it tightened...and using a SIX point socket also helps in many cases. On SUPER NICE jobs...I will not paint them and reapply the coating like they were originally that you can get from Eastwood...which seems to work fine.

That is why I spray painted the brackets and bolts. I also found the
longer you wait to install the parts, the better the paint holds. At least
for me, I had to touch-up very little when I installed everything, but it
was probably months from painting to install.

Thanks for the compliment.
Finally getting to drive mine around again after setting for
20+years. I know you will enjoy yours when you finish.
Just don't get discouraged, it took me 3+years on mine and
I still need to repaint sometime in the future.

Yes spend 12 months so far, but plan to have it ready for next summer, but it should be pretty rapid progress as I have restored all the parts as I have removed them which is pretty much everything under the hood, lights are all restored and back in place and all the rest are ready to just bolt back on.....just hope I can remember where everything goes!!
