The kit has it all. It only comes with 10 inserts though (1 head). You have to get 10 more inserts. I would think the dealer would be the most expensive place too.
Look at the timesert website. Look at the head gasket repair thread and look at the link to the writeup on timeserting.
There is also a similar product on ebay. The inserts look a little longer. I havn't seen anyone use them though. I would think it would work as well as timeserts but I have not used this kit.
