Shown here is our Comp Cams 10 degree "Super Locks." These are a huge, extremely beefy valve lock which has a wider angle of interference than a standard 7 degree lock. These are fully machined (not stamped) from a super tough fatigue resistant alloy. Comp recommends these for any cams over .460" lift (basically anything other than bone stock) but we feel they're absolutely necessary above .510" lift. These fit 11/32 valve stems, which can be found on most aftermarket aluminum heads (such as our Stealth heads or Edelbrock RPM's,) and they work great with our Comp "Super Lock" retainers, part number 145-1003 or 145-1006, which can be found on our Valve Retainers page. We highly recommend upgrading to these for extra insurance, and it's required if you will be running a cam over .510" lift. These are supplied in a set of 32, enough to do one complete engine. Since they're Comp, you can be assured of two things: They're 100% made in the USA, and the quality is second to none.
These are the Comp Cams 7 Degree stamped valve locks which we supply in our Stealth Cylinder heads. Designed for single groove valves. We offer them separately for service replacement purposes. Recomended for maximum .510" lift applications. Complete set of 32 pieces.
This is a labor charge for us to remove and replace valve locks and retainers only, such as when changing from a 7 degree to a 10 degree setup. This basic head labor charge does NOT include replacing valve springs and seals, please select our extended head labor charge if you need valve springs and seals replaced also. This labor charge must be selected in the same order as the cylinder heads, along with the new valve locks and retainers you want upgraded. Does not include custom shimming each spring to a specific installed height.
