2.0 head on 2.2 block?
has anyone ever heard of this being done? i found a 2.0 head for $350 and figured since i might have messed up my head from my turbo i might go wit a 2.0 head. will this work? if so wat differences have been made?

Why don't you just port and polish your 2.2 head and buy stronger valve springs and cams. You would require a new tune because i believe the 2.0 cams have a slightly different grind to them than ours

GM build book used the LSJ casting on a 2.2 block, as it is a better designed head from the get go.
The LSJ head uses different cam castings, but the grinds are the same. I believe you could use the 2.0 head without any actual modifications, the 2.2 doesn't have the cam sensor, so the LSJ sensor won't be an issue, just leave it unplugged.

well im not sure that the cams can be used but dont hold me to that since anythin is possible. they have the same grind as the 2.2 its just timed different is what i've always heard. so basically you might would need adjustable timing gears to actually make up for the difference in the timing.

ok i wasn't sure if they had the same grind pattern to them. If i was you i'd buy some turbo grid cams and stronger valve springs, would be nice but then your bottom end would need some stronger parts.
What exactly is wrong with your head right now?

positive would most likely be the fact that the timing on the lsj cams are for F/I so that should be a plus. down side would be if you couldnt use the cams.. lol

Use either cams, as long as you time them for the 2.2, the timing will be the same. The 2.2 blanks fit in the LSJ head physically, but they don't have the cam sensor, so the LSJ guys can't use them. In your case, pop your 2.2 cams in, block off the cam position sensor, and you will be fine.

i'd reccomend a turbo grind cam. if you do a little research on the subject you'll find that the sc and turbo grinds are different when it comes to timing of course it'll work but i found that the sc grind is similar to na grinds and turbo grinds are modified to flow differently when it comes to the int. and exh. vavle timings cause they don't require exh scavaging. if you do go with the sc grind get a bov if you don't already have one.

Yes it does have a sensor. If you just look at the cam gears they MAY have marking for 2.2 timing on them. Never looked so i'm not sure, but you could probly just bolt your cam gears from the 2.2 head to them cams in a 2.0 and be fine
