I just recently purchased a LH6 with DOD. I've done a few searches and have gotten conflicting information. Some say you have to change the lifters, valley cover, oil pump etc, but I talked to another experianced LS guy I know and he said I could get away with only replacing the valley cover. Sorry if this has already been discussed in another thread. I searched but couldn't find a clear answer.
