Comp 901 valve springs,and retainers,locks.
I would avoid the Comp Locks and Retainers , my builder stopped using them and I have posted pics in another thread of the locks that I just took off after 5 years and 25k miles they were a C hair from failing completely , I am running single bee hive springs so the pressures aren't that big but they are shot . Another member here posted pics of his new retainers after less than 100 miles and they are all cracked , what ever people want to say to the contrary based on past product quality the reality is they no longer sell a quality product when it comes to locks and retainers .Here I copied the pic for ya , this is a single groove lock with just a hair of the ridge remaining .
