if its a block get a 6 bolt... otherwise I can pull those engines apart and the ONLY gasket I need is the headgasket.
Keep both manifolds on it (detaching the exhaust mani. from the turbo), keep the thermostat housing on it, just detach at the tube. Take off all the wiring (CAS, injectors, idle air, TPS, throttle closed, ignitor, coils). Take off the upper intercooler pipe keeping the throttle body elbow. Detach all the vac. lines going to the head (I think FPR, the 4 on the TB, one to the BOV, mabye more).
Depress the timing belt tensioner to put slack on the timing belt, and slide the timing belt off the cam gears. Pull the valve cover off (just pull the spark plug wires off and leave them connceted to the coil). Now pull the... (If my memory serves me right), 10 head BOLTS (or studs if using ARP).
Get a friend, one of you grab the head by the cam gears and other person by the back of the intake manifold and thermostat housing (i.e. one person on the left side of the car, one on the right), and pull the head off.
ONLY gasket exposed will be the head gasket. If its a bad headgasket replace it with a new one... the METAL 4-layer Ralli-ART one only costs like $90:

If it needs a block get a 6-bolt (90-92 talon/eclipse/laser/galantvr4) block and swap it in. That way you have the strongest block and the car will never crankwalk.
