Effects Speed??

Effects Speed??


For some reason all of my effect speeds look the same no matter how
fast or slow I put them.
Here's my code. I've tested a bunch of scenarios with different speeds
and the speed keywords. They all look the same. The ID's header1 & 2
refer to images is that the cause? This is for a website image
rotater. Any Ideas???
header1();
    function header1 () {
        time = window.setInterval(function () {
            clearInterval(time);
            $("#header2").toggle("drop", { direction: "right" }, 100000);
            time2 = window.setInterval(function () {
                clearInterval(time2)
                $("#header1").toggle("explode", { pieces: 25 }, 100000);
            }, 400);
            header2();
        }, 5000);
    }
    function header2 () {
        time = window.setInterval(function () {
            clearInterval(time);
            $("#header1").toggle("drop", { direction: "right" }, 100000);
            time2 = window.setInterval(function () {
                clearInterval(time2)
                $("#header2").toggle("explode", { pieces: 25 }, "slow");
            }, 400);
            header1();
        }, 5000);
    }
