SOURCE: what is the firing order
What you need to do is...
1, Find TDC (top dead centre) for cylinder number 1. Easiest way to do this is to get the car on level ground, put it in 5th gear, handbrake off and pull / rock the car forwards. You are looking to line up the timing dot on the crank pulley to the notch on the cover. At the same time observe which direction the rotor arm turns as well i.e. clock or anti-clock wise.
2, Once you have found TDC, look to where the rotor arm is pointing and that will be towards plug number ones lead position.
3, Now assuming the firing order is 1-3-4-2 and #1 cylinder is at the opposite end to the gearbox, you should be able to work out what goes where.
4, Look at the rotor arm position as you have set up the timing, fit the cap then fit the lead to #1 cylinder. Fit the other leads as above.

I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.
