I finally listened to your engine video - sounds good, but needs to be sync'd (as you already know). Baby steps on the syncing process. These things are more trouble to set up than a big block, but once sync'd they're pretty smooth.
Love those mufflers - similar to my Bergs but quite a bit quieter. What are they, again?
Oh, and I envy that fancy timing light/tach/dwell gizmo. I think my timing light (a wand powered by 2 "D" cells) is something like 35 years old.......
