I am going to guess you picked several out and tried to link us to the "compare" page. Well that wont work.
On header bolts there is no need for anything too fancy. Most "bolt loosening" problems are due to gasket compression. I use cheap bolts and check them frequently for a week or two after installation and have no problems. Fanciest bolt I would consider would be the ARP with the 5/16" 12-point head which might make wrench clearance a little eaier.

Like I said header bolts looening only happens because they loose torque when the gasket compresses. The right solution is frequent retightening if using a gasket that compresses. There are some that do not compress, but still good proceedure to check them frequently at first.
