ARP Head Bolts are as essential as Engine Oil for your 7M Motor. If you want to ensure your block and head stay as tight and sealed as possible ensure you use ARP's on your 7M. When asked we always recommend ARP Head Studs over head bolts simply because they are threaded on both ends of the stud so have greater clamping force.
ARP uses premium grade 8740 alloy that is rated far superior to aircraft quality. Each stud is precisely heat-treated to 200,000 psi.
