I think you are about right on the eyebrows; I use that + 1 more cc for the gap down to the top rings. I get your identical SCR if I use your numbers.... good to see that both our numbers are on the same page! That means that the DCR numbers will agree too as long as we use the same intake closing angle.
Ok I did 4cc for the eyebrows and that puts us at 7.92:1 do all 318 have the eyebrows ? Is there a chance mine dont? Just curious we will find out soon lol.
