Engine Mechanical problem
1996 Saturn SL2 4 cyl Front Wheel Drive Automatic 135000 miles

I own a 1996 saturn sl2 and i'm trying to remove the head of the engine to check out the head gasket and the cylinder walls to make sure they're ok. Long story short the engine started making a loud knocking sound the other day, then it erupted in smoke and lost almost all power and then stalled at every stop. I know it's probably shot to hell and back but I would still like to check. I've removed the valve cover, timing belt, camshafts, a/c compressor, exhaust manifold, and the head screws in and around where the valves are, i've removed the belt from the side of the engine, and disconnected the battery terminal and took out the tubing from the throttle body. Even after i've done all that it still won't come off. Can someone please give me a list of all the things I need to remove to get the head off? Thank you ahead of time!

Ok first off thank you for responding I really appreciated it. I followed your instructions to the t, but the head still won't come off. I know sometimes it can be glued or stuck together after years of usage so I tried hitting it with a block of wood and a hammer towards the firewall, towards the headlights, and I even eventually tried using a crowbar to pry it straight up in case there were sleeves in the head bolt holes. Nothing worked and I still haven't been able to get the head off. Any other advice?
