well guys my motor is deff on its last leg, it gurgling while its runninmg (still runs). when you hit the gas it cuts out as itsa revving, when it ideals it thumps every half second, i tried turning up the idle it works until u hit the gas. so here is one last pic of the hf motor before she comes out

any ideas what might be wrong? I figured maybe the head gasket
