    It is indeed a deal, as long as the Northstar keeps behaving

    Just be sure to change the coolant as soon as you buy it, and every 2 years after and it should be OK, the pulled head bolts are not as terminal as it was a few years ago. Now that there is a repair kit available that does not require the engine to be removed, just the heads.

    Using Heli-Coil inserts with complementary headbolts would also have worked. The following electrolosis to manifest between the coils and block would have glued them in and not have had any detrimental effect on the bolt to coil thread surfaces. I guess, this procedure was too expensive for GM to use

    Or just using course thread bolts would have helped, the fine tread bolts used don't allow for much damage to the threads.

    Nobody but GM ever uses fine threads in aluminum. Who do they have there coming up with such hare-brained designs?

    GM counted on the head gaskets never blowing until long after the car was gone after even extended warranty. I can vouch for personal experience. Trust me - you can do all factory maintenance and still get screwed.
