Instead of shelling out for ARP bolts, Head down to your local CAT dealer
and buy your bolts there. Should be cheaper than ARP as well.
CAT bolts a manufactured to extremely high standards. I know of a number of guys that use them in their race motors with no problems.
Cap screws are generally rated to Grade 12.9. Which is high, Most high grade bolts are Grade 8.8.
