Valve setup for 216 TDC

I was putting my 1940 216 together on the stand and I wanted to set the valve clearance. Of course I didn't have the flywheel on so I used the position of the lifters to deduce the proper spot for TDC. I noticed that there is a hole in my balancer just inboard of the pulley and it was at the very bottom at the time. I am wondering if that hole is there for reference.

If that is in the face, that where material was removed to balance the balancer.
Here is one on eBay with two holes.

I guess I am just lucky but now I have a handy reference. When I put the flywheel on, I found out I had it half way between the triangle and the ball.

If you can't see any timing marks, using tappet motion isn't as easy as it looks - both valve are closed for a long time in these engines.
To help: the cylinders run in pairs. When one of each pair is @ TDC on compression (with both valves fully closed), its partner is @ TDC on overlap and has its valves moving in opposite directions. Pairs are separated by 3 places in the firing order (1 5 3 6 2 4).
Pairs are 1 & 6, 5 & 2, 3 & 4
