ok, i got done installing my head that ert built, and after having to jump the car a few times, it was running good, idling kinda funny, but im sure that was because of the S2 cams, so i took it for a drive around my house, and it was driving fine, still idling weird but nothing worrying me, so i decided to open her up a bit, got her to about 4k rpms, and stopped the car, and the lights started to dim, rpms dropped real low, and it was strugging to stay alive, and it died, so i coasted it back to my working spot, tried jumping it, but all that was happening was the starter was spinning, so i look at the timing, and the exhaust line is facing middle, while the intake is facing upwards, and the belt is loose, and i can take it off, but the guy who helped me said if i bent valves, i would have heard a sound like pap pap pap, and it would have been loud, but i heard nothing like that, it just died and wont crank, any ideas, please, i need my car back
