I read probably a dozen different threads on the subject before I went into this but most didn't address these points. 1. don't attempt to take off the lower manafold off the head while it's in the truck - almost impossible. 2. really pay attention to the routing of the lower wiring harness: the basic layout is pritty simple but i didn't watch close enough to which side of certain hoses etc it ran on. ended up threading it though the truck a few time only to have it not fit (close but not close enough). 3. go ahead and get new head bolts along with a new gasket. i found a bunch of threads on broken head bolts, stripped and difficult to remove head bolts if i searched for it specifically. I was lucky to have the correct size tap to chase the threads otherwise, get one of those too. 4. even with all the pictures i took, there were a couple of vacuum lines at the end which were very difficult to remember where they went.
