Degreeing Cam by Measuring Overlap @ Lifters

Thanks for the replies and clarification. My timing chain was stretched enough to knock against the fuel pump arm so I figured since I am replacing it might as well go further and learn about degreeing. I have only put together a few engines and always did a dot-to-dot and go which worked but I have never been able to really dial this engine in. Excited to see if it makes a difference.
