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.

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.

GT40X Heads Will this head bolt kit work with GT40X heads?


  • Hi, This ARP High Performance Series Head Bolt Kit - Hex will not work with GT40X heads you will need to use the Ford Performance 289/302 Head Bolt Kit Item #50146 because of the special step washers needed since the GT40X heads have larger ½” bolt holes for 351 motors. Here is the link

    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.
