1997 Mitsubishi Eclipse

Noises problem
1997 Mitsubishi Eclipse 4 cyl Front Wheel Drive Automatic

i ran my car low on oil and I turned it off. When I started it up half an hour later it had a loud tick that doesnt go away, its there at idle and it gets a little louder with higher rpms than idle. Im pretty sure its in the head cause the tick is higher up sounding in the engine but I dont know what it is. My friend thinks I have a bent vaulve so if you think its a bent vaulve how would I know it is without takeing the head completly apart. I have already takein the head off the car. And all the vaulve faces seem fine. The exsaust vaulves are a carmal color and the intake vaulve faces are black. I found that odd, but the guy I bought it off of said it was a fresh rebuild with about 1000 miles on it. It is the turboed eclipse with a 4g63t engine. Oh and the piston faces seem to have no scareing ether and the camshaft lobes seem to be fine too. I dont know if any of that helped, I also kind of hot roded the car 10 mins before I turned it off too haha. Thats probably why it has the tick now, but anyways thank you for listening and let me know if you can help me
