On hondas there is some extra work involved, it doesn't just bolt it on and work. The oil passages on the VTEC head don't match up with a NON-VTEC Block. It requires doing work to the head, or using a oil line routing kit. Don't know if thats the same case for these 2 motors or not. But if you just slap it together, and don't know what your doing, you won't be just putting the stock motor back together and slapping it in without a full rebuild. You get it wrong, and you starve the engine of oil which will damage every moving part. My advise is to check some cavalier/cobalt forums and see what they are doing. If it's even somewhat easy there will already be people doing it that can give you the info you need.
