can i reuse head bolts?

so i've finally got garage time lined up at my buddies to do the top end on my duster. offy intake, 390 holley, headers, high compression head, mopar performance cam. just a couple questions before its go time.

first, can i reuse my old cylinder head bolts?

next, when installing the new cam do i need to replace the cam bearings? are there indicators that they would need to be replaced? never done a cam swap myself.

also, is it too much to paint a /6 hemi orange? i just love how the color pops out a you when you open the hood. plus, it would be really wild with the lime green car.

i am freaking excited to get this done!! i've had all my parts sitting in my storage unit all winter, waiting for garage time, and it's finally here!! cant wait to post some pics/videos of my new setup.:-D
