    Flathead Cylinder Head Stud Kit

    Performance engine builders know that head studs are superior to bolts, and this is especially the case on Flathead Ford and Mercury V8s. Flathead decks are thin and their threads are easily stripped. By installing studs, you avoid damaging the threads in the block through repeated use. The combination of the studs' fine outer threads and hardened washers also prevents galling and ensures accurate torque readings, particularly on aluminum heads.

    • Studs utilize superior "pull down torque"
    • Properly fastens and torques both aluminum and iron heads
