    Gonna keep the hsv vn v6 i picked up and since im gonna keep it im also gonna make it 100% orignal again, only got to change parcel shelf. plastic around parcel shalf and put a standed tape deck back in it.
    But the reason i was gonna sell it was because i didnt have time to play with it and i couldent be bothered to fix the headgasket,but now i have afew hours every weekend to give it some lovin, Just wondering if anyone has any tips or info they wish to give me about changing the head gaskets(Series 2)

    Take it slow....

    Head gaskets are fairly straight forward to do.

    Remove the accessories that you think may be in the way.
    Drain ALL the water/coolant out of the motor
    Pull the inlet manifold off
    Pull the rocker covers off
    Crack the head studs
    Pull the heads off
    Clean the old gasket off
    Ensure the surface is clean and flat
    Replace gaskets
    Replace heads and accessories
    Done.

    If you are going to keep it for a long time, and keep it original/standard HSV I would
    consider rebuilding the engine and getting a set of change-over reconditioned heads.

    That way while the motor is out you can tidy up the rest of the crap easier. Detail the engine-bay, paint the motor, etc.

    Let us know how you go with it.

    **Wish i coulda bought it!

    I'm pretty sure you just make the area as clean as possible, using contact cleaner or similar, then place the new head gasket on.

    Cheers.

    No, dont use gaskiet goo on the headgasket.

    Also, remove the exhaust manifolds completely (they get in the way) and for reassembly, undo the flange at the front of the cat and the clamp just forward of that.

    Put some kind of assembly lube on the head bolts before you put them back in. And if you have to remove the rockers, keep them in the correct order or they will not go back on correctly.
