I can't find the thread but there used to be one on drilling the 2 small holes to match the head gasket behind #4 piston, does anyone remember this and what's the theory behind it?
 
I was remembering a different thread, there's more in these ones about running extra lines from the head to the upper radiator hose. I went ahead put two 1/8" holes in it. I've done it in the past to no ill effect that I could tell.

Ignoring the previous links (too early, not enough java yet), I recall that Towery added these holes and had the details on his old PBase pics. Seems HE had a link to the origination ..... Group A racing perhaps?
