  1. Head gaskets blown on LLY

    04.5-05 LLY Duramax Powertrain
    Blew the head gaskets out on my 05 LLY, and sounds like it's going to cost more to fix then what it's worth, been looking at swapping motors to an LBZ, what would I have to change in order to get the LBZ to work? Also looked all over and the only thread I found was from 2011 and didn't give any...
