1.345 Valve Springs - Ovate Beehive (16)

The 1.345 Valve Springs - Ovate Beehive (16) by PAC Racing Springs represents a purpose-built component for serious engine builders and performance enthusiasts seeking maximum valve control in high-rpm applications. These springs are engineered to maintain consistent valve seating across aggressive cam profiles, preventing float and ensuring reliable valve train geometry even under extreme lift conditions. Whether you're building a street performance engine or preparing a track-focused power plant, this spring set delivers the stability required for modern valvetrain demands.

PAC Racing Springs' ovate beehive design distinguishes itself through an asymmetrical cross-section that reduces coil bind while optimizing load distribution across the spring's working length. The 1.345-inch outer diameter and beehive architecture minimize spring mass without sacrificing stiffness, a critical advantage when targeting higher rpm ceilings where inertial forces accelerate valve train wear and instability. The 16-piece set provides complete coverage for a full 16-valve engine head, with each spring precision-wound to exacting tolerances that ensure uniform preload and response characteristics across all cylinders.

Performance builders and engine shops rely on PAC Racing Springs for compatibility with both stock and aftermarket cylinder heads featuring standard spring seats and retainer geometries. Installation requires careful attention to spring seat condition and proper shimming to achieve target installed height, a detail that directly impacts cam timing accuracy and valve clearance. These springs pair effectively with upgraded pushrods, rocker arms, and solid roller lifters in small-block and mid-sized engine platforms, making them essential for anyone serious about eliminating valvetrain compromise during high-output engine modifications.
