Thanks tlowe, How critical are the keepers? Most of them have a little even wear, but the ones that were missing the shields have a little depression where the leading edge of the spring has worn in about .001 The rockers show some wear as well, but nothing I can catch a fingernail on. I was thinking I could smooth that out a little with a piece of 600 grit and some oil. With the hydraulic lifters I am thinking that the absolute overall dimension from the face of the valve to the face of the rocker is not that critical?
