    Big bore head torque problems

    Since installing the TB parts V2 head and 67mm big bore cylinder & piston, my head bolts keep coming loose and causing a head gasket leak.

    The head bolt studs have now started to pull out of the cases - (one of which had to have a timesert installed.)

    Has anyone else experienced this ? And any solutions ?

    Any feedback or suggestion is welcomed

    Thanks
