It seems that the head has to come off again, maybe I am better of to get another head from a junkyard, I have been to so many local junkyards around boston that they know me by my first name, have never done a valve job before, so the learning curve probably would make it harder than the head gasket job that I have done twice in the last 2 years.(I have the original head in storage, the reason I got the head from a 98 900 2.0L was availability and my fear that the original head which was resurfaced for the 1st head gasket job would not stand another resurfacing, would the valves from that head work, just flip flop)
By the way SWEDECAR you where right on the camshafts be slightly diffrent on the 98 turbo 2.0L, when I put the original camshafts, it worked, even though I was getting 17 mpg, it was running and I blamed the low mpg on the cell from o2 sensor which I replaced during the recent timing chain job, if the valves from the original head can be exchanged with the one's in the car, how much of a headach is that and do I need special tools(valve spring compressor, probably AutoZone), and does the head have to come off anyway.
Now as a reminder this is how I got here.
This is the story anyone with any ideas please post this car is killing me (LITERRALY)
I exchanged a 98 900 2.0L head for my 94 2.3 non-turbo
a few modifications were required(temp sensor, plugin next to temp sensor had to be closed, but the camshaft were plug and play, now it is not leaking fluid into oil, but it is choking, and dies if you push the gas pedal, I think it's leaking air from exhust manifold, hence it is losing pressure, the oil and water are both clean, o2 sensor malfunction?
any help is appreciated

I don't clearly understand if you choose to keep the turbo camshafts in the head or not? That wouldn't be good.
Are you absolutely sure you got the cam timing correct?
O2 sensor could have been damaged by the work or coolant but you would have a check engine light in that case.

The camshafts are exactly the same with the exhust side having the end for distributor to plug into, I matched all 3 timing notches and rotated 2 turns after I put the timing chain back on and they were dead on, this head had less places for studs for exhust manifold than my own, and one was busted which I jerry rigged but not sure if is perfect, I cleaned both surfaces of exhust and head to put the exhust mani back on, but used the old gasket which came with the turbo and look to be in great shape, and the old studs which again looked to be in good shape, when the car ran at the beginning it let a lot of smoke and some from the area near the exhust mani to the head connection, in any case it turns and runs but as soon as press the accelerator pedal it huff and puffs and gets choked and dies AND THE ENGIN SIGN comes on, there is no oil in water or water in oil, so the head gasket is ok
On the o2, can I read the code I have tried to use the wire technique that new generation web site shows, but it has not worked for me, I read somewhere that I should put a 47k resistor parallel to it and it works but have not tried it, any helps is appointed

Loosing air from the exhaust manifold should not cause so much problems. Did you make sure the valves were sealing properly on the new head. If the head is stored with the cams in place some of the valves will be open. Debries can get to the valves and in time will cause them not to seal properly. If you then put the head on the car the engine will not run properly. Do a compression test to make sure you have good compression. Was the head from a 2L turbo. If so the CAMs will not have the right profile and could cause problems at full throttle were the fueling is controlled by fixed fuel maps stored in the ECU. At normal speeds you air mettering system should be able cope (If you have a MAF (mass air flow metering system)).
