Texas Speed & Performance is proud to offer the latest version of the best dual valve spring kit on the market!  This kit now includes our patent-pending Precision Race Components integrated seat and seal.  You no longer have to worry about special installation tools for your valve seals, tearing a valve seal upon installation, or valve seals popping off!  Our new integrated seat and seal will work with factory-size valve guides and CANNOT be used on any aftermarket bronze guide applications!
The polished TSP .660" spring kit featuring PAC valve springs is the newest offering in valve spring technology offering the latest processes and material for maximum spring life.  PAC Racing is a leader in valve spring technology, so it was only natural to team up with the best in the valve spring industry for our latest offering in a valve spring kit!  We have developed a .660" dual spring kit with the help of PAC Racing that still offers excellent valvetrain control, even for the more aggressive hydraulic roller camshafts.  These valve springs will offer excellent durability and stability and will work well with factory-style lifters.  PAC polishes the valve springs, which helps to increase the overall life of the springs.  This greatly reduces the chances of spring fatigue and failure.  PAC's polishing process is completed without losing any pressure in the valve springs, so you maintain all of the capabilities of the non-polished version.
