Original equipment on many Gen I High Performance 302, 327 and LT1 350 engines from the 60’s.

After all these years, they are still popular with the high performance Hydraulic cam street scene.

Basically, these work well with many hydraulic cams with under .500" lift.

Duration @ .050” should be kept under 240 degrees.

Although we recommend they are use with our chrome molt steel retainers and locks, they can be used with stock retainers.

Applications with over .500" lift can consider one of our many high lift spring kits listed in our store.


NOTE: Heads which came with rotator retainers on the exhaust will need to replace them with actual retainers. If your heads have rotators, consider one complete spring kits instead. Due to a lower spring base location on the exhausts, some 305 heads with factory installed rotators will not only need to purchase a kit but will also require offset locks and additional shims to aid in acquiring the target installed height.
