There are some additives being made, but the brands escape me at the moment. When I had the engine in the race car done a couple of years back, the builder (well respected in this area) told me to use about a 1/2 quart of break-in oil with the regular oil if you cannot find some that has the ZDDP in it already. Soem brands still do and it seems that there is more being marketed. It is also a good idea to use weaker springs (or just the outers) during engine break-in to relieve some of the seat pressure.
