I did them myself....
No problems with the original bolts but I live in Qld so corrosion is a non entity - you shouldn't have a problem but if you're in the Southern States, maybe the wet conditions can corrode the bolts.....they are only 6.8 carbon steel.
I do recommend a good torque wrench though, the bolts screw into relatively soft alloy cylinder head, and the last thing you need are stripped threads!!If you fit an afetrmarket header, you may have to enlarge the holes to make sure the retaining bolts don't go in scew.
