    Default Head stud sealing.

    Hi fellow LTX enthusiast, I have a question.
    I'm do research on the best way to seal up head studs on your blocks do to the fact that your blocks are not blind hole. I do not want to have them leak on my procharger build

    Indian head shellac on threads of stud, let tack then thread into block. Or get fancy with arp sealant

    Do not use the ARP stuff.

    RTV for myself and @blackbirdws6

    Another vote for Permatex here too. Used it multiple times without any issues.

    Never would have thought of using black RTV.

    Up until about a year ago I never stopped to think that I was using a gasket maker/sealer to seal threads. My shop teacher in high school always insisted we use rtv on the threads of water pump bolts and I just always did it on head bolts that went into water jackets too.
