Why Upgrade to ARP Head Studs?
Because head lift is not a personality trait—it’s a problem.
Head studs provide more consistent and even clamping force compared to bolts, which is critical for maintaining a proper seal between the cylinder head and block—especially in turbocharged or high-compression builds.
It is for just right reason that almost each most sensible professional engine builder depends upon ARP Pro Series head studs for his or her all-out competition powerplants. Simply stated, there’s now not a greater stud setup in the marketplace nowadays.

Why It Matters
Using stock head bolts in a performance build can lead to:
- Head lift under boost
