Re: timing a 51 EAB flathead
2 or 4 degrees is a minor detail since the factory provides the "bump" and the pointer; just align them.
For what it's worth, I always use a vacuum gauge to set initial timing, especially on modified engines. I disconnect and plug that vacuum line at the distributor and turn the distributor to obtain the highest vacuum reading. I then retard it a tad. This method has always worked well for me.
