Title: Block cooling holes
Post by: SuperSix on August 08 2011, 09:30:15 PM: I noticed these holes were almost 100% blocked by the head gasket - aren't these coolant passages?

I had already poked out the top two when I took this pic.

Not sure if that version of MSPaint will resize the pics - you can try.

Post by: Just a Six? on August 12 2011, 08:48:28 AM: Being so small makes me think they are steam holes. The end ones are the main water flow & these would be mostly for steam I think?

Yours kinda looks like mine. Little holes from the factory that went 117k.
