What tools are needed to remove timing cover and heads

While changing spark plugs I dropped a bolt down intake. I need to pull head so I can remove from the cylinder.
Do you
have the same problem?

Welcome to 2CarPros. Well that isn't going to be fun. However if you dropped it into the intake I doubt it went into the cylinder itself. The valves don't lift that far and the bolt would need to make it around a few turns to get into the head itself. I would try using a small flexible magnet to gently reach into the intake ports and fish it out. If it did make it past the valves which would take a very small bolt. I would use a magnet into the intake with the valves as far open as possible, then use an air nozzle to move the bolt toward the magnet. Before I did any of that I would get a small inspection camera so I could look into the spark plug hole and down the intake to be sure it really made it inside and where. Wouldn't want you to pull the head and when you tip it up the bolt falls out of a port.

If you are sure it went into the head then. You may as well replace the timing belt, tensioner and water pump as well unless they have low mileage as the belt has to come off to get the cam out of the way to get the head off.
Tool wise you need the proper wrenches, a torque wrench and a torque angle gauge for the head bolts. Plus new head bolts as they are torque to yield.

Using the 4 step torque-turn method, tighten the head bolts according to the image and to the following torque values:

- Step 1: 45 ft. Lbs.
- Step 2: 65 ft. Lbs.
- Step 3: Check again for 65 ft. Lbs.
- Step 4: Now turn them each another + 90

Inner timing cover to cylinder head bolts. 40 ft. Lbs.
Hold the camshaft sprocket gear and tighten the camshaft sprocket bolt to 85 ft. Lbs. Plus a 1/4 turn.
If you need more info just ask.
