in process of getting new valve seals as well as valve spring retainers for my 105# springs. someone from CGP said i can get the Fel-Pro brand that advanced auto sells, but needs to be the viton types. i called advance auto and the guy said they only have the Fel-Pro Premiums part #SS72144. he doesnt know if they're the viton type since it'll need to be special ordered. So my question is rather than pay the vendors(no offense) for a set of valve stem seals with mark up, can i get away and use the ones advance auto or pep boys sell?
thanks in advance.
also-if anyone haslower mileage or NIB valve spring retainers for the 105# springs please PM me
