So I read that a lot of folks were swapping the 6.5 head gaskets on their engines when turboing them. I pulled my heads off, and bought some 6.5 head gaskets, as I was matching them up to the heads I noticed that they cover up a couple of the holes where coolant flows through. I got HGs for a 1993 6.5 turbo diesel engine. I am putting them on my 84 6.2. Am I supposed to just cut them out, or what?
