    Will these bolts work with GT40P heads?

    • Yes

    Helpful (1)

    Is this kit for both heads? Do i need to order anything else besides the head bolts?

    • The ARP High Performance Series Head Bolt Kit will contain the hardware for both cylinder heads.

    Will these work on Trick Flow Twisted Wedge 170 ?

    • Unfortunately we have not tested the ARP High Performance Series Head Bolt Kit on the Trick Flow Twisted Wedge 170. Since we have not I will not be able to guarantee perfect fitment. I personally do not see why they will not be compatible with that setup.

    Helpful (0)

    Are these compatible with Trick Flow Twisted Wedge 170 heads?

    • Unless otherwise stated by the Manufacturer of the Heads, these bolts are sufficient for the installation. A quality set of studs is also an option and highly recommended.

    Are these TTY bolts? Can they be re-used?

    • Some later 5.0's had tty bolts, these are not. Just follow arp's procedure and specs and they can be reused.

      SBF ARP headbolts

      Used these on several occasions, never had any issues. Tried another brand once and had a bolt shank break and land about 20ft away, several weeks after being torqued, while still on the engine stand. ARP's quality is definitely worth the price.

      Torque To Yield head bolts

      I didn't realize these were TTY (Torque To Yield bolts) and for one time use only. They installed fine on my 1989 5.0 motor, but I would have liked the regular reusable bolts as I like how you torque them down to a specific value instead of adding an extra 1/4 turn for these ones. Plus, of course, the regular ones are reusable.
