Cam degreeing double check

In 1966 this 19 year old went down to Chet Herbert to get my first roller cam and after telling him what I had and wanted to do with it he put a cam wrapped in paper and a box of rollers on the counter with 2 long 1/4" square rods. Explained how to soak the rollers and lube the cam lobes. I then asked him where to degree it to and after a bit I think he realized I was not really getting it. I had the positive stop TDC down ok but was a little vague to the rest. He rolled over to his desk and picked up a steel rule and said get it on TDC with the cam at overlap and use a .025 feeler gauge to set the intake above the exhaust. He also told me how to adjust the valves (in when ex start open/ex when in starts to close). Just leave that dial indicator alone for now. It still works for me today. I had no idea how much I did not know.
