    Custom Four Valve Heads

    Mercury Racing designed, Edelbrock ® cast DOHC , four-valve cylinder heads.

    • Intake and exhaust port flow is significantly improved over conventional 2-valve heads for improved drivability, idle quality, and torque compared to a high lift 2-valve design
    • Efficient, high tumble four valve combustion
    • Low mass, high stiffness design reduces stresses and enables smooth high RPM operation and long life
    • Intake valve heads are 43.25 mm (1.703 in) diameter
    • Exhaust valve heads are 36 mm (1.417 in) diameter
