Recommendations for engine paint and exhaust manifold coating/paint??

[Econman]

I'm getting my engine back from the machine shops next week and want to get the paint ordered while I'm doing the assembly.

What suggestions can you give on brand/type that is the most durable and looks best? I'll be using Chevy orange and some semi-gloss black for pulleys, brackets and breather and silver on the exhaust manifolds.

Thanks in advance for your suggestions!
