Blown head gasket?

There are 14 head bolts with the 10mm hex holes. The larger aluminum ones, (4) hold the plate for the spark plug boots, the others in the head go into the water jackets, leave them alone. You can take off the ones that hold the spark plug boots, I think they are 12 mm, but it isn't necessary to remove them, but cleaning under them is easier. Just get a good 1/2 in breaker bar, about a 6 inch 1/2" extension and the I use hardened reducer to 3/8" and then the 10mm allen socket. They are on at least 55 to 60 lbs of torque. And like was mentioned earlier, make sure the inside of the head bolt is clean so you can fit the allen socket all the way in the bolt.

Let us know how it goes.
