    Head Gasket help

    Hi All, I had a rebuild completed by a Shop, here in Down Under machined block and machined head fitted OEM 260 gasket was running real nice approx. 10 hrs old, then started overheating on WOT! Typical signs bubbles in header tank
    I am running C kit Charger with all the Mods
    my question is using OEM Headbolts or Arp Studs?
    I was told the OEM head bolts are good for my set up @ 16psi boost
    was really impressed with the rebuild until Now!
    getting it repaired shortly,just after input on what to use
    TIA,

    First, what year is your machine? It sounds like an issue with the cooling system. I have a 2014 rxt x and with closed loop and a 160 tstat the cooling system had trouble keeping up with only a 137 wheel when the temps were warmer but only at wot for extended periods. Ended up going open loop and that alleviated the problem. As far as head bolts or studs I personally prefer studs. Being the bolts are torque to yeild sometimes they dont stretch properly.

    What type of rpm are you turning?

    Heís right. Head bolts wonít cause an overheating problem. Your cooling system just canít keep up. Did you try it without a tstat?

    Are you running stock compression pistons? How aggressive is your tune?

    Got to find the cause of the head gasket failure or it will happen again.

    At that rpm there was coolant shooting out of the overflow for the coolant tank on mine when it was closed loop. I thought it was a head gasket but it was mint. Turns out the coolant system was just over pressurized because of the rpm i was spinning. So what makes you think you have a bad head gasket? Just because it is over heating?
