    Speedway Motors 9108918 Details

    The flathead Ford V8 was designed to run on fuel with high levels of lead, but even with leaded fuel, the stock valves will eventually hammer the seats out, which will close up the valve lash and leave your valves hanging open...that is if you don't seize a valve to the guides first!

    Remember what year your engine was built and how fatigued the valve train components are. Henry may have built them right with the technology he had available then, but this is now and we have the modern components you need.  This kit includes everything to rebuild your Ford Flathead valves, including intake and exhaust valves, seats, guides, and retainers.

    • 0.060" oversize valves and seats
    • Hardened intake 30° valve seat
    • Hardened exhaust 45° valve seat
    • Hi-grade 4N stainless valves, full machine finish
    • Heat treated valve guides
    • Valve guide retainer clips
