    ✅ Solving EJ Series Problems
    Known for head lifting and cracking, the EJ20 needed a robust solution. PRP's cast head offers improved intake port spacing for larger valves, thicker head material, and a redesigned exhaust port for better flow and reduced back pressure.

    ☝️ Why Cast Over Billet?
    While billet is great for prototypes, casting is ideal for mass production, offering better thermal expansion properties and consistent quality.

    🔥 Enhanced Performance
    The new design supports 14mm head studs and versatile coil mounting options, making it easier for high-power builds. Customizable port designs allow for CNC porting up to 420 CFM, ensuring optimal performance.
