The Chtrysler chart was "borrowed, copied," from GM on thier SB valve lash setting procedure, lets see what are the stock cam LSA on a SB Chevy in 1955 compared to todays racing LSA, esepcially on a Hemiriod motor OP, another way is to bring the motor up so the distributor rotor is pointing at #1 wire and adjust that cylinder, rotate the motor 90 degrees clockwise to #8 and do that one and go on down the firing order. I could do it(intake open adjust the exhaust and the rest of the way Bob wrote about ) with a socket and breaker bar manually so I can watch the timing marks on the dampener, this is on a race motor with a degreed dampener that shows a mark every 90 degrees from TDC You can mark yours also or buy and use a timing tape The 90 degree method works fine on stock cams, the other way is better on large duration race cams
