Have a Nice Day? seeking advice on how to identify a JDM ej20 STi motors generation!

about 8 months ago i bought a 1994 impreza wagon with a JDM ej20 STi swap that i was told was for the 1999-2000 gen JDM STi's, but i'm not entirely sure now.

long story short it got stolen, i got it back and now it has a bunch of problems. my main problem is my head gasket leak, among other things.

SOOO my main question is are there any distinguishing characteristics of these JDM motors that would tell me exactly what version/generation the motor is? i don't want to buy the wrong gasket set and this would greatly help me in all aspects of working on/building my car.

please help me out! is there some spot on the engine where i should be looking for some sort of stamp or parts number?

any advice would be very, very much appreciated! i want to move forward to the next stage of my build, and i need this gasket fixed first!

thank you so much for checking this out, i very much look forward to responses!

Yes, 99-2000 would have a coil pack on the manifold off center (ver. 6 ej207) Pre 99 would be coil pack on top in the center vers. 3/4 (Ej20k).

Edit: I also believe ver. 1/2 was coil on plug.

Post pics of the engine and we will tell you what it is. Anything else will be a waste of time.

Post the timing belt cover sticker number if you have it still on the black cover in the front That can distinguish its year, model, etc. a google search of that number might bring you some results also if its a common engine. There is also a forum topic on here (sorry i dont have the link handy) that was made some time ago that lists the timing cover codes to all the models so if you do have that sticker thats what id try first.
