12 initial is quite conservative, I bet the engine would like 15-18 as long as it doesn’t effect engine cranking but every combo is different.

Everything I've read about these heads says you don't need as much timing due to the chamber design. Most of the SCJ threads I've read have 12 to 14 degrees initial and 28 to 30 all in by 3000.
