    Post head gasket job issue

    So as I posted in an earlier thread, I tore down the top end of the motor to replace a bad lifter that was squealing. So the issue was in cylinder number 8.

    Not sure what I have in there...

    I've recently replaced my rear shocks and now I need to work on the front. I'm not sure what's in there now but I took a picture and it does have a resistor connected. So I'm assuming I don't have to run air shocks in the front now? But if I can get some opinions, it would help tremendously...
