After rereading the post, those holes are something else, the temp sensor is in the front head only and in the front side center. Possibly compression release holes if they go into the combustion chamber or I've heard of people talking about predrilled compression releases in SE heads that are just guide holes that need finished off but I thought that was just a Twin Cam SE head?
What are the part numbers stamped in the castings?

Lonewolf, good possibility of dual plugs but the mentioning of blind holes has me throwed off in this one. Should be able to see an exit into combustion chambers

I agree to that point. I've seen blind holes for dual plugs before. They just weren't finished to give a race option.
