Application:

These Sure Seat valve springs are essential components when upgrading to Edelbrock Performer-Plus camshafts on stock cylinder heads. Using the correct valve springs as specified by Edelbrock is critical for maintaining camshaft warranty coverage and ensuring proper valve train operation. The springs provide the necessary tension and control to match the camshaft's lift and duration characteristics while preventing valve float at higher RPMs.

Edelbrock's Sure Seat valve springs utilize the same proven design and materials found in their complete Performer and RPM cylinder head assemblies. This ensures you're getting race-proven technology that's been tested and refined for street performance applications.

Note: For camshaft warranty compliance and optimal performance, always use Edelbrock-recommended valve springs for your specific camshaft application.
