I went to a scrap yard today and saw a ASTRA GTE but the guy there told me it is a 1.8 engine. I thought it looks more like my 2.0 engine. He will let me have the CAM out of it. I suppose on the GTE the CAM must be 20SEH type and also I suspect the 1.8 GTE will have the same CAM anyway wouldn't it? The only thing that puzzles me though is that the ASTRA has the new head bolts which means that the head must have come out at some stage in its life. Who knows there might be a different CAM in there all together. Is worth a try I think.
