As usual another bad head gasket on a northstar, but I would like to know what else I should replace. I don't plan on rebuilding the heads or re-ringing the pistions, but with 150,000 on the odo. I know there are some precautionary measures I need to take. Anyone have some good info?

 

to me at 150000 on odo if you do just the head gasket dont be surprised if you spin a bearing. once that antifreeze gets into the engine you may as well look for a replacement
