Valve Seat Technology for Stock and Performance Applications
Valve seats are a critical
engine component because they are the foundation of the valvetrain. The seats
provide a surface for the valves to seal against when they close so there’s no
loss of compression or pressure from the combustion chamber. The seats also
help cool the valves by conducting heat away from valves into the cylinder
head.
The seats also support the valves and determine installed valve height, which affects valvetrain geometry and valve lash. The diameter of the seats and the contour of the angles that are machined into the face of the seats also limit how much air the engine can flow at any given valve lift and rpm. Because of all these factors, the valve seats deserve a lot of attention whether you are rebuilding a stock engine or building a performance engine.
