Yeah it will work ok. The comp ratio will drop a little so you could get the head skimmed to bring that back a touch. You can use a 2.0 inlet if you re drill the manifold mounting hole positions to suit the 2.2 head. Basically a 2.2 std head is as good as a reasonably ported 2.0.

matt24680 Posted November 9, 2010 Author Share Posted November 9, 2010 hi there thanks for the reply i have bought the 2.2 ported head so does this mean i have to use different spark plugs ,ht leads ,exhaust?also if i want to put a kent or a piper cam on should it be made for a 2.2 or a 2.0? thanks Quote Link to comment Share on other sites More sharing options...
Exclusive Opel Posted November 9, 2010 Share Posted November 9, 2010 I'm running a 2.2 head on a 2.0 block. I'm using the 2.2 inlet manifold. 2.0 exhaust manifold. Same plugs,leads and exhaust. Added the fifth/cold start injector to the inlet manifold. 2.0 air flow meter, tried a 2.2 one and it doesn't work. 2.0 throttle body on the 2.2 manifold (2.2 one's different?). The distributor I'm using is a Carlton one though not sure for which model but seems to work well. Using a 2.0 cam. It does run very well from freezing temperatures to hot days without any pinking. It's not going to break any speed records though Set the engine up three years ago and not altered anything since so something must be working right! You will need a 2.2 thermostat housing. Someone else will need to confirm if an adapter plate can be made to use one from a 2.0 engine, sure someone has said it can be done. Have some pictures somewhere of the head and manifold together if needed. That's all I can remember at the moment. Did you buy the £500 head on ebay a couple of weeks back? ebay Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted November 10, 2010 Share Posted November 10, 2010 (edited) hi there thanks for the reply i have bought the 2.2 ported head so does this mean i have to use different spark plugs ,ht leads ,exhaust?also if i want to put a kent or a piper cam on should it be made for a 2.2 or a 2.0? thanks No all cams etc are the same. Some of the valve springs from cam manufacturers are 2.0 or 2.2/2.4 specific but its no big deal.You can make up an adaptor plate to use the 2.0 stat housing, just got to be careful about clearances. Oh and either use the 2.0 head bolts or buy cap head 12.9 bolts as replacements as the stretch bolts that are available are pretty crap.

matt24680 Posted November 11, 2010 Author Share Posted November 11, 2010 hi there thanks for the replys its this 1 how can i tell if the valves are for unleaded or not?:unsure:sorry im a bit clueless http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=290495419145&ssPageName=ADME:B:EOIBSA:GB:1123 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted November 11, 2010 Share Posted November 11, 2010 so long as its date stamped inside 85 or 86 & has p22 on the side it will be ok for unleaded. you will be able to see the exhaust valve seats very clearly around the edge of the valve.it should show up as a very distinctive insert of a shinier metal in a perfect circle rather than a machined area of the casting only.

The head you have has 46mm 214n valves by the look of it on the inlet side but the exhausts look std. If you want to check them they' usually made by rec so have that stamped round the collet part of the valve. Only reason i say is because the std 2.2 valves will be two part valves, ie cheap stem with a higher quality head friction welded to it. These can snap off if your revving them hard or if the head of the valve has been machned to improve flow. Worth checking if your gonna be revving it hard as it can kill the motor if it happens. And yes i have seen this on 2 or 3 motors. HTH Chris Quote Link to comment Share on other sites More sharing options...
moodoo Posted August 31, 2012 Share Posted August 31, 2012 Sorry to drag this one up again...see post 7 above...my head is stamped '85', but only '22E', not P22E...any idea if that means she's good for unleaded or not? Part number stamped on head is 90209816 if that's any help? There are no seats installed, but posts I've read on here somewhere and on opelgt.com reckoned that they had hardened areas manufactured into the head instead of inserts??

lamchop77 Posted September 1, 2012 Share Posted September 1, 2012 (edited) From what i have read on gt forums its the early 1.9 head that had the flame hardened valve seats not the 2.2 heads. Every 2.2 head i have has inserts, if yours has been ported then you might not be able to see them. If in doubt get inserts fitted, they will go in as the head castings will all be the same. If you cant afford to get it done then run the engine and keep a check on the valve clearance, if it starts to close up then your getting valve seat recession so you will need to get them fitted. If you do get them fitted you will also have to redo the porting round the insert. HTH Chris Edited September 1, 2012 by lamchop77 Quote Link to comment Share on other sites More sharing options...
moodoo Posted September 3, 2012 Share Posted September 3, 2012 Thanks Chris. Now would definitely be the time to do it if I'm going to. Best thing is probably to take it to the machine shop and ask them to take a look. It's funny, if you look from the top, it's like you can see the outer edge of an insert (you can see the change from dull to shiny in the pic), but theres absolutely no join in the internal wall of the port, where the bottom of the seat would show. Maybe that shiny area is just where it's been ground for the bigger exhaust valves. Any idea what maximum outer diameter of exhaust inserts you have used is? Given that there are 42m exhaust valves in this thing, I don't want to let the machine shop screw the head up if they go putting seats in with too big an OD! Thanks, Fin Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted September 6, 2012 Share Posted September 6, 2012 Mine have 41mm exhaust valves in and theres enough room. Another 0.5mm shouldn't be a problem. If you take it to a machine shop find out what valve guides have been fitted, i'd be interested to know want to fit them to my heads.

monzta Posted September 25, 2012 Share Posted September 25, 2012 Regarding thermostate housing the ones from the c30ne are identical and may be easier to find. Quote Link to comment Share on other sites More sharing options...
