I'm in the middle of doing a HG on a 7mgte. The water jackets on the head had large amounts of buildup. I chipped them out best I could. Now question is, on the exhaust side, #2,3,4,5,6 the water jackets have 2 ports for flow, one towards the front and in the middle. But #1 only has the middle port. I dug and it doesn't seem to have the forward hole. I just wanted to confirm that #1 only has the middle hole. Wanna know before I put the head back on. I've done a few HG but never paid attention to this area. I tried searching but couldn't find a pic/info.

Here's a pic at an angle that only shows the middle hole.


Thanks

Ok, #2 in this pic is the middle hole which all cylinders have. But #1, only cylinders 2,3,4,5,6 have it. This pic is at an angle that would hide it if it did have a hole there.



The head had sooo much buildup that cause overheating, which led to BHG. I'm just wondering if I need to continue digging for a hole, if it is there.

you will never find a hole there.. There is not one.
Here is a pic!


Just got finished with a head gasket job myself.
