Once this is done, you won't need to adjust the lash very often, although you still need to occasionally check it. A good time to check the lash is at oil change intervals or before competition. |

| − | + | *On a SBC and most other V8s, you can cut the center out of an old valve cover to use when setting lash hot, engine running. It will keep most of the oil from splashing out. *Using feeler gauges bent at a 45 degree angle (you can bend them yourself) will often make adjustments easier. | |

A tool like that can even help when setting the lash cold because it's easier to get the same 'feel' from valve to valve. |

| − | + | *A go/no-go feeler set is not expensive and will make ''checking'' the lash ''uber'' easy. Use a standard feeler gauge for adjustment, not the go/no-go feelers. The two sizes on one blade are usually 0.002" apart so the first, thinner section will fit but the thicker step shouldn't if the valve is in adjustment. | |
