Well first of all, you want to take your block to a good machine shop to have it checked out, cleaned, magnafluxed, and new soft plugs put in. It might need bored out...mine did....20 over. Also the crank might need turned. You will need an engine kit....the shop that I had my machine work done at, also got me the kit. This included a complete Fel-Pro gasket kit. New timing chain/sprockets, cam, bearings, lifters, etc, etc. The engine kit was like $700 something and the machine work was a bit more. Also get the heads checked out....that was $180 more. Other people on here can probably tell you more than I can, but these are costly engines to rebuild....while you're at it, you might as well rebuild the tranny too. Be patient and get a manual for torque specs, etc. And also have a nice bank account.
