Best 18 degree head out there?

Did you ever verify the mark on the balancer to make sure it's indicating true TDC?

Screwed up dial back timing light?? Friend of mine had one that was about 6 degrees off.

I have 2 lights, one in garage and one in trailer (same brand) both read the same. Same lights as I have used past few years. I always check all that out when assembling the engine and degreeing the cam. Only other changes from last year is Q-16, bigger converter, and vacumm pump.... dunno? It likes the timing.....
