Pulled this head off the 1030 with the broken block. Both heads have the plastic inserts on the corner ports. Don't pay attention to the other ports, they are plugged from a mouse. But the corner ports have those plastic inserts in them in both heads that were on the tractor, I haven't found the third head yet which is supposed to be in the shed somewhere. Anyone else seen those before? None of the heads I've seen from my 400 to Jeff's 2394 have had them in, including the 3 from my other 1030. Any idea if they are supposed to be there and what they are for? This tractor has had over heating problems since new and I'm wondering if this could be the cause.

After a call To TW cable, I'm able to post again. As per our phone conversation,here is a pic of my 931 head. Same hole you posted. 9/32" drill bit fits easily. 5/16" is snug, but maybe just some scale in hole. I didn't chuck the 5/16" bit in the drill and try it. I think your heads are factory correct.
