Valve springs with larger diameters require retainers to handle the higher pressures developed by the springs. COMP Cams steel retainers are precision machined from chrome moly steel and finished in black oxide. These precision retainers are specifically designed for positive location when combined with COMP Cams high-quality valve springs. For superior strength and ultimate stability, both 7 and 10 retainers and valve locks are available.

Did not fit the 916 springs as advised by comp. I remachined them to be spring locators....so now i don't need any shims.

OEM keepers are not 10 degrees so you will have to buy the correct keepers. Can be frustrating because my heads had three differently grooved valves.
