        5 Top Rated Questions

        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.

        Helpful (0)

        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.

            Comes with everything needed including sealant/lube for the threads. Bolts threaded nicely and torqued down with ease.

            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.
