Help an old man tune a new to me 340

So, I run the Summit Billet distributor that uses plastic “keys” that you insert into the advance plate to adjust your mechanical advance. The difference in the keys thickness changes the advance. I run 23 initial and 34 total, which was easy to get. For me, I just taped a degree wheel to the distributor gear and held the distributor in a vice. Made a pointer and moved the advance weights out. Looked at how many degrees it turned and x 2 the number. Thats how much mechanical it has. Got me close enough to only do it once. My initial isn’t hyper critical to me. So I got it close and set my total after. Was shooting for 10 degs. Got 11 degs Understand my engine is NOT apples to apples to yours by any means. But I like the distributor.
