Yep, I agree; I get SCR = 10.65, with the same head gasket. DCR end sup around 8.2 for that cam at an ICL of 106. Should be runnable on pump premium; take care in tuning.
That is all at sea level.
What elevation are you at OP? If up at 3000' then DCR drops over half a point, so you might want to re-think if that is the case, depending on what you want to do with this. What is the planned use of this engine?
