Default Rebuilt 400 HO suddenly runs rough

Car also runs a bit hot now.

I have the service manual. It says to set initial timing at 6 degrees BTDC. I thought with today’s gas, that this wouldn’t necessarily be applicable anymore.

Also, my balancer has two marks on it that are 6 degrees apart. I’m not sure, but I’m assuming that the engine builder added the second mark. I would think that the bottom mark is 0, and that the top one represents an additional 6 degrees BTDC.
