Thanks! Got it bookmarked now! I'm going to be building a couple of "261's" before too long, (more like closer to "300") and I might be using 848 heads, or possibly milling one of the earlier low compression 235 heads to get the same compression ratio. Either way, I'll need to drill those holes. The standard 261 head with the holes already there can also be milled to duplicate the 848 combustion chamber.
