Default 95 ej22 heads on a 97? Dual port goodness...

So... I am trying to drop a 97 Ej22 from a manual car (i.e. no egr) into my 95 Impreza with an Auto (egr) My question is this: Can I just take the heads off the 95 and put them on the 97? That way I can still have the egr and not have to change to a single port. I also won't have to change anything with the exhaust too so it would just be great. If I was able to do this what Head Gaskets would I use... Oh yeah I am in Cali if that matters and I do try when possible to remain smog legal.

Yes you can just put the heads on. Both years use the same head gaskets.

It's really that simple? Sounds too good to me... I got one side off on each motor today and they look the same as far as how they connect and all that so I am stoked to find out it will work (I was worried about there being something crazy like a .000001 difference that would cause a cataclysmic failure or something) Thanks for the response! Anyone else see a problem with this? If I read the same thing twice on the internet it MUST be true. Haha. Thanks guys.

Yes, everything is just about the same. The 97 shortblock has slightly different pistons with no valve reliefs. It will very slightly bump the compression up. From about 9.5-1 to 9.7-1. One downside is the engine will now be interference type. If the timing belt ever breaks it will bend the valves.

Just like my WRX! Sweet! I guess this is also code talk for replace the timing belt while you are in there... Now I just gotta figure out the timing thing. Back to the search feature for me!

Anyone have any Yoda like advise or wisdom to contribute to my replacing this timing belt? I have done the reading and research but am still kind of leary since this is now an interference engine... Oh well, back to my Marine Corps days I guess. One Shot, One Kill. Hopefully it won't be my engine dying.

It's very easy on a 2.2. The marks on the cam pulleys go up and line up with the marks on the timing covers. Use the mark on the back of the crank pulley and it lines up with the mark on the oil pump.

if you reuse your belt tensioner, compress it VERY slowly as they like to break when pushed in too fast. use a small hex key or something in the hole to keep it depressed.

new is nice and saves worry!

So the broken bolt needs to be drilled out and the hole most likely most likely sleeved... This is going to run me between $200 and $300 dollars. Now I am debating whether to press on with this build or just start looking for a donor block. Anyone have an EJ22 block lying around that is not going to take a crap load of work before it's functional? I just want this car running already...
