Retainers and Keepers

   
   
   
Keepers and Lash Caps  

Most common configuration
Square Grove (chevy) ,10 degree keepers, separate lash cap (short), keepers are cut to fit and support the lash cap.

note: there must be a small clearance between cap and keepers

 

Round Groove  
Square Groove  
Note: Keepers should be above retainers and start to sink as the retainers stretch and fail

Integral keeper and lash cap, may be straight or puzzle seam on top, may also come as matched pairs, round or square groves, 10 or 7 degree.

second grove in keeper to lock cap on valve stem
this would be very difficult to "fit to valve", and make sure only keeper is clamping valve and cap is only pushing on valve
