2.8 Heads/Improving Cooling.

[M3xpress]

I've got the heads off my B2 and I remember reading something about drilling extra holes in the heads to improve cooling.

Does anybody have or know where I can find the diagram of where to drill?

I've never seen a diagram but the tech. library has a description of where to drill. One guy on here wrote not to long ago that he did that.
