A final note comes from a guy who also had a blown head gasket:
Quote:
The exhaust Side head bolts were definitely not anywhere near torque spec when i removed the head, it only took about 1/4 turn on my 1/2" drive ratchet to get them to loosen by hand and this is the side that has the water jackets busted through completely in areas on the gasket and....
the intake side bolts (the ones under the valve cover) all took the expected amount of effort to remove about 2-3 turns before hand loosen-able so what i've read about cast iron blocks with aluminum heads having issues with metal expansion being too great on the exhaust side the cylinder head due to heat and eventually causing blown head gaskets makes sense from what happened to my engine.

It looks as though it would be prudent for all owners of this engine to have the front (exhaust side) bolts checked,
as they seem prone to loosen or else aren't always properly tightened.
