Set of 16 performance valve springs for your IH V-8. Have you ever wondered why your IH engine won't rev beyond about 4500 RPM? This is actually not a bad thing...Like a built in rev-limiter? It is primarily because the springs are soft and it is getting valve float. These will make sure that doesn't happen. Matched for Schneider Cams
Includes: 16x performance valve springs
