Please say you have a Haynes Manual

Just in case you haven't noticed, the heads are connected to each other via a timing belt. Since your post doesn't mention that the timing belt has been removed, I thought it worth bringing it to your attention.

The intake must also be removed. Again, you didn't mention this was already done.

You should be at this point (with the timing belt rear cover plate also removed) before attempting to remove the heads.


Also, if you don't already have a Haynes manual, go drop the $20 to get one. Best investment you'll make if you plan on doing a lot of your own work.

No offense (I really mean this in a nice way)... but it sounds like you have no idea what you are doing. Have you ever rebuilt (or even taken apart) an engine before?

A ratchet? The ratchet will help you remove all accessory pullies... A pulley removal tool aka "Pulley Puller" will help remove the crank pulley.
