Profiler 12 Deg timing

[Jts1360]

What kind of timing is everyone running with this head? NA no nitrous......

[JWRE]

Of course there are other variables that determine it, but most of the engines I build using that head end up with around 30* timing. Most are in the 15 to 1 range and use C-16 fuel. I always start with 28* and go from there. Some stay at 28* and others have gone as high as 31*.
