ARP Bolt Kits

If you use arp stainless then yes they are stronger, however if you use regular stainless steel bolts then they are not as strong as grade 8. I learned my less on my heads about stainless and now I am using only ARP or grade 8 bolts.. if you are using stainless make sure you use antiseize on the bolts.

oh and stay away from alloy boltz.com, their ss bolts break really easily.
