    It’s easy to assemble a show-quality engine when you use ARP’s handy Engine & Accessory Fastener Kit. Virtually everything you need comes completely organized in one convenient package.

The stainless steel is polished to achieve a brilliant luster, and provides a distinctive, maintenance-free environment. Each kit has a dozen different type fasteners, all neatly organized and labeled in protective vacuum-wrapped packages. 

    • 12 point heads
    • Polished stainless steel 300 material

  • Flathead Ford Heat Treated Valve Guides
    Flathead Ford Heat Treated Valve Guides
    (Part #91015315)
    x
                

    The Flathead 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.

    These Flathead Ford valve guides are heat treated to be compatible with today's low-lead fuels. Fits 1932-53 engines. If using in a 1932-48 engine, you will have to use 1949-53 style retainers, keepers and valves.

                Valve springs with larger diameters require retainers to handle the higher pressures developed by the springs. COMP Cams® Steel Retainers are the perfect solution to this problem.

The retainers are CNC-machined to exact tolerances using CAD/CAM software. All COMP ® retainers use only high-grade SAE 4140 chromemoly steel with no lead, <0.04% sulfur and a black oxide finish to prevent corrosion. COMP Cams ® Steel Valve Spring Retainers offer both unmatched looks and superior performance that set the industry standard.
