What ya trying to accomplish?
Both 1.9 ltr engines use the same block. The heads are interchangeable to a certain extent.
The 96 and 97 SOHC heads had some casting flaws and were prone to cracking.
Some slight changes were made from generation 1 sattys to gen 3 sattys. Different EGR valves, one temp sensor instead of two, and so on. If you need to pass an emmisions test be sure things are compatible.
Not sure about the groove you mention. No rockers on overhead cam engines so no adjustment possible.
Good luck and let us know. :)
