New head bolts and studs on rebuild?

I am rebuilding the top end on my wr400f 1999. Doing a 420 big bore and Hot Cams exhaust cam. I was planning to get it done today but got to thinking about the head bolts and studs.

Do they need to be replaced Or can I reuse the ones I took off?

Any help would be much appreciated.

No problem reusing them but take a good look at the treads to make sure there not stretched it should be fine but doesn't hurt to look at them.

I found this pic in-case your not sure what your looking for
