I like that they are stainless 12 point, they add a little extra detail that I enjoy looking at.

Just like all of ARP's other products, these bolts have very nice rolled threads, a smooth underhead flange, an appropriately sized washer, and a precision head. These worked nicely to fill the four longer bolt holes on an Edelbrock intake manifold for my Chevy 454 (the regular intake bolt kit comes with all 1" bolts, but four need 1.5" bolts in order to engage enough threads to properly clamp).
