Do I need another distributor now?

I’d be highly surprised if your new Holley doesn’t have a vacuum advance port. Might be in a different location but it should still have one.
If it doesn't it’s not that difficult to modify a distributor for mechanical only advance. It’s just basically a change of springs so the advance weights swing out faster.
