Alex GL-10 Posted April 1, 2006 Share Posted April 1, 2006 I was looking at my heads to day and they say EA82 underlined. The block has EA82 with a box around it. Does that mean I have a gen. 3 block with gen. 2 heads? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted April 1, 2006 Share Posted April 1, 2006 All the block markings are inside a box - even the EA71/EA81. The EA82 head castings were made different to distinquish them. There is no "gen" for EA82 blocks. For that matter there isn't even a difference in blocks - they are all interchangeable - different pistons on some tho.

calebz Posted April 1, 2006 Share Posted April 1, 2006 Small difference in blocks. The turbo block has a hole in it for the PCV, whereas the carb and spfi blocks do not. Turbo also has an oil seperator plate that the other don't Overall, little things. Link to comment Share on other sites More sharing options...
