Even after 150K miles the cam looks good. Measured the lifters and all are within .005" of .272". I am not sure what the OEM lobe height should be. I never could find the number listed anywhere. It looks like .272" is the nominal dimension. The wear pattern on the cam and lifters look good so I am keeping them. I do not want to replace the lifters without replacing the cam. And it looks like I don't need to replace the cam at this time.
