Agree.
Do you have a place to attach an old fashioned timing pointer, like on the timing cover, so it will be reasonably close to the front dampener without hitting it?
They have piston stops that screw into the sparkplug hole. Put a piece of masking tape all the way around dampener. Rotate both ways until you hit the stop and make a mark on the tape next to the pointer when it stops from each direction. Then split the difference between the parks and call it TDC. I think they also sell thin metal timing tapes for common size dampeners. Just line up zero at your TDC mark and attach the tape.
You could also use the 40rpm drop rule. Adjust timing for max idle rpm and then retard it until the rpm drops by 40.
If your exhaust is quiet and your ears are really good, then you can advance it until you her a little light pinging and then back it off a little. Then see how it feels. But your exhaust better be quiet and your ears better be pretty good for you to do this. ;-)
Let us know if you have further questions.

A timing tape is necessary unless your dampener already has marks on it.
There is a way to do it with a timing light but I've never done it that way. You will need to figure out a pointer bolted to the block somewhere to mark tdc on your timing tape once you have that established.
Hope this helps!
