Questions & Answers
Will these stem seals fit with stock springs and retainers
By Anon.
Yes, they'll work with OEM valve components. As you've probably read in the description, they're required only if you're using Kibblewhite valve spring kits. Otherwise, they'll work with OEM or OEM-spec replacement parts.
