. . . I am under the understanding that there is no difference in volume using the 848. . .
If there is no difference in the "volume" when using the high compression 235 head compared to the lower compression 261 head, how do you think the 235 with a high compression "848" head achieves that high compression?
There was a post a while ago about drilling the additional coolant passages on the "848" head at an angle. Maybe someone will post info on this? I think the drilling information might have come from the Inliners International discussion board?
