IRON ALLOY VALVE SEATS
FOR STEEL VALVES
•Premium valve seats for applications using steel valves
•A specific combination of alloys allowed a creation of high density, iron-based valve seat with uniform hardness,
exceptional thermal qualities and high resistance to wear and recession caused by microwelding
•Only by using the latest developments in powdered metal technology were we able to blend these alloys to give
a seat material with the qualities required for today’s engines
•These seats have been tested on the track and street in high RPM applications with leaded, unleaded, and
oxygenated fuel, as well as methanol, ethanol, nitrous, and forced induction applications
•Sold each
•Made in the U.S.A.
NOTE: All applications listed use two intake and 2 exhaust seats unless otherwise noted.

INTAKE ONLY CONVERSION VALVE AND SPRING KITS
•Stainless steel conversion kits include only what’s needed to convert your head to the long-life stainless steel Black Diamond intake valves
•Extends the life of the valvetrain and intake components by as much as 4x over the OEM titanium parts
•Includes forged one-piece stainless steel intake valves, wound chrome-silicon heat-treated wire valve springs, ultra-light titanium retainers and hardened
steel bases
•Components are created using Finite Element Analysis (F.E.A.) software, as well as proprietary camshaft analysis and spring design software
•Specifically designed and engineered for each application
