RE: first time head swap
Take your time and double check your torque specs and sequences. Keep all your bolts in labeled bags or something to keep them organized. Here's a step by step that I found to be about 98% if you'd like to take a look at it, it's very helpful.

For heads, it's pretty straightforward. The link someone gave should help. When putting the head bolts back in, torque them in increments (while following the torque sequence, of course). For example.. if the torque spec is 75ft-lbs, torque them all in sequence to 10. then 20. then 40. then 60. then 75. And research your bolts on the part mfr's website, some require you to untorque and retorque them all several times, some would get damaged by doing so. Just go ARP, and you don't have to retorque em anyway.

Torque Specifications, Sequence, and Firing Order
Disassembly:
Mark all your hoses and connections with the tape and marker to help you put it together later on. Take pictures if need be. Relieve the fuel pressure by either having the car sit for a few hours or remove the schrader valve cap and use a small flathead screwdriver to press into the valve and release the pressure. Have a towel handy to absob the fuel that will come out. On 87-95 cars the schrader valve is located on a fuel rail located behind the alternator. Remove your air inlet tube whether it be a cold air intake or the stock plastic air box. Remove the MAF by undoing the connection from it. Begin to remove the throttle body by unbolting it from the 4 studs screwed into the upper intake held on by the 4 matching bolts. Also release the TPS sensor (on top of throttle body) connection along with the throttle linkage that pops off. Unbolt the upper intake (6 bolts I believe) and make sure you get the ones underneath the upper intake plate held onto it by some screws. Prepare for later to possibly replace the bolts or reuse them depending on what intake you are going to use. Before lifting it off completely remove the vacuum hoses from the upper intake so you can bring it up without tearing a line. When you unbolt the upper intake before hand it gives you more hand room to get those hoses and lines off nicely. The distributor is held in by one bolt located on the right side of the shaft. Make note of the firing order and where your spark plug wires went. Put a paper towel in the distributor hole so you don’t get any tools or debris in the engine.
Now that the upper intake is removed go ahead and unbolt the 4 bolts that hold the fuel rail onto the lower intake. On the front passenger side head bolt, the fuel rail is held on by a bolt to hold the rail in place. Unbolt it so you can swing the fuel rail out of the way once you remove the rail from the injectors. The injectors will just pop out of your fuel rail and lower intake. Your local parts store will have a/c & fuel line disconnect tools that will let you disconnect the fuel rail easily. Unbolt the thermostat housing, which is held on by two bolts on the front of your lower intake. Go ahead and loosen all the 12 bolts that hold your lower intake on. The lower intake will be a bit hard to get off. Pry it off carefully and remove it after you have the hoses, sensors, lines removed from the lower intake. Swing those connections out of the way. Now that both the upper and lower intake are off it would be a good time to “reinstall” the upper and lower intake sensors and hoses onto your new intake.
Next I would go ahead and begin to remove the radiator and pull it out along with the fan shroud and stock fan and fan clutch. Remove your overflow tank. Unbolt the a/c condenser (in front of radiator) and swing it out of the way. This will now allow plenty of room for you to pull and install your cam later on. Start to remove the accessories on your engine. The alternator is bolted onto a bracket, which is held on by 3 bolts. Undo the alternator connections and remove it along with its bracket. Next remove the smog pump, if equipped, and then remove the a/c compressor by removing the bolts and swing it out of the way as well so you do not “bleed” the system and have to refill that later on. Next remove the power steering and remember how all the accessories bolt up for future reference.
Removal of the harmonic balancer is next after you remove the four bolts from the crankshaft pulley. And you have to break loose the 15/16th bolt that holds the balancer on. Put your car in 5th gear or Park with the e-brake on and someone stepping on the brake, if need be. You can then put a break-over bar and turn it counterclockwise to break the bolt loose. Removing the balancer is next. You need to get a harmonic balancer removal tool from your local parts store. Take bolt out and remove the washer. Thread the bolt back in about half way in. You are now ready to bolt up the harmonic balancer puller and use it. Next I would remove the water pump and timing chain. To save time and a gasket you can remove them as one piece. Try to remove the bolts/studs out carefully

RE: first time head swap
You only have to torque the heads down in 3 steps, usually it's something like25-50-75. i torqued the short ones to 80 and the long ones to 90 on my build. The engine prime tool is nice but is it really necessary for heads? All the oil drains off them when your engine stops normally anyway.

If you do end up priming the engine and don't want to buy a tool, there's a cheap way to do it, but BE CAREFUL- get a 12" extension, and duct tape a 1/4" socket to it. It's basically a ghetto priming tool, and works just as well. But like I said, make sure that thing is on there, or you'll end up with a socket in your oil pan, which will put you in a whole world of hurt. I made one, worked fine for me but I was reeeaallll careful to tape it well and test it beforehand
Edit: fixed dumb mistake
