Hardened head bolts
170,000 psi rated erl racing hardened head bolts new in the box. I opened noticed I had the wrong bolts for my application these bolt apply 2004-2013 ls1 motors. Complete set both heads with washers. Installed the top 5 10mm only and took them back out no force applied. Asking 80 bucks you pay shipping.
