Review on 🔩 Enhance Performance with the ARP-434-1102 Stainless Steel Header Bolt Kit by Cory Jacobson

Pretty good head bolt set but probably overpriced for what it is. Interestingly, the factory bolts now have a large hex head. These ARP bolts still mimic the old stationary manifold bolt that broke off over time. If they don't suffer the same fate, they're worth their money. The screws also come with a set of very good washers. These are not ordinary flat washers, they are smaller in diameter and about twice the size of regular stainless steel metric flat washers.
