Case Review
When Balford designs a valve spring cup, we always include a draft angle and a vent groove, and we recommend using valve spring cups on all springs — they protect the head and shim, and locate and align the spring during assembly. These valve spring locators are stamped from thin cold-rolled carbon steel.
