So. I'm redoing my heads on a 2.4 Ecotech LEA because timing bent valves. So, I got the valves cleaned them up and now I'm trying to figure out what the valves should look like with the head off and in time because when I put the head on and I timed it correctly, the engine would not turn over. I checked camshaft caps they are all on correctly. I'm trying to make sure I didn't miss anything for when I put it back together because some valves are open and some aren't. The picture attached shows the intake at 10 o'clock and exhaust at 7.

I don't see any images. Please allow time for them to load before you submit your response. Here are how the timing chain marks are supposed to look, there is a procedure and a special tool needed to do the job. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

My intake valves are open at TDC, why would that be?

Try turning the crankshaft 360 degrees and recheck. Please send images of the problem.
