Headers

[97snakedriver]

Looking at my directions that came with the FRPP units I have sitting in my living room it says:
To replace them you have to:

1. Remove H/X pipe assembly.
2. Remove secondary air connections from the front of manifolds.

Then Passenger Side:

1. Remove Starter
2. Loosen exhaust manifold nuts
3. Remove the motor mount bolts and raise the engine 1 1/2 inches
4. Remove old manifolds, and install new ones
5. Lower engine back, and re-bolt studs
The Driver Side:
6. Re-install the starter

1. Remove the steering shaft
2. Remove dipstick tube.
3. Remove old manifold and install new headers.
4. Put everything back together again, start and test for leaks.

There's more detail to it, put that's the overview. 10 hours sounds like a bit much, but it doesn't sound easy.
