Header Bolt Differences
http://store.summitracing.com/Compar...SKU=CLO-C-3039
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.

All of these bolts have an underhead length of 1.000 inches. I am guessing the $16 bolts will work just as well as the $33 bolts.
