i didn't. just clean them up good and use anti-seize when you go to put them back in.

It's probably better for you in the long run. When i did my installation i used my old ones and forgot to clean the threads out, got misthreaded, and had to Re-Tap the header. It was not fun. Although not necessary to buy them, they can't be too expensive... Just make sure you get some good ones if you do (not shitty ones that will break), and torque them to spec. After a week of driving it if you didnt use anti-seize retighten them to torque spec again, they'll shake loose from heat and vibration a little bit. Good Luck.

maybe i got lucky but i re-used my bolts and gaskets about 6 times. they should be ok

i thought the bolts suplied by Kooks were junk compared to the stock bolts. I compared the two and it clearly looked like the factory bolts were stronger. rule of thumb : if it doesnt thred in by hand dont put a wrench on it.

I know there expensive but the arp header studs are awesome it you dont mind shelling out 100$ bucks. No cross threading worry or nothing and they make the install easier'
