Question about high mileage maintenance, I will now be driving over 600 miles a week Options

[HaysoosKreesto]

So I got a new job and will be commuting roughly 600 miles a week. What can I do to ensure the functional response of my car for the many miles ahead? Currently it has about 177k miles on the stock engine.

Here is a list of some of the things I think will need to be changed:
- Head gasket
- Waterpump?
- fuel filter?
- spark plugs
- Brakes

Here is a list of some of the things that I have already changed:
- Thermostat
- radiator
- Tires
- coolant temperature sensor
- Oxygen sensor
- catalytic converter
- Timing belt was changed at 148K

Any suggestions of what else needs to be changed?

Well if you do the head gasket, you might as well pull the engine and get the head and block decked so that way they're machined flat so you won't have issues with the new head gasket.
Waterpump should have been replaced when the time belt was done.

You're really over thinking things. Just get a new distributor coil, cap, rotor, plugs, and wires, keep up on your oil changes every 4k or 5k (which ever you prefer).
If your car is having fuel issues then replace the filter? I believe I still have the OEM one in my car at 279k.
You only need to change your pads and rotors if A) your pads are low (just replace pads) or B) your rotors are bad. If the rotors are bad, do rotors and pads all around.

Maybe change your power steering and alternator belts too if they're getting worn out?
