First, if you have broken studs you’ll need a welder and some nuts. Even if you don’t it’s possible one might break when loosening so go slow.
Needed flex head ratcheting wrench for some spots and open end wrench for others. Could only get a socket on a few bolts with various extension combos. In hind sight, I would have trimmed the shields off the gaskets before installing. They just get in the way and slice your hand like butter.
Hardest part was getting that first bolt in. These headers do not have open slots to hang them on during placement. An extra pair of hands would help but it’s a tight fit up in that wheel well. Also, you will need to reuse a bolt for the dipstick bracket with the supplied spacer so don’t toss your old hardware.
You will need to disconnect the steering shaft on the drivers side and bend the dipstick tube out of the way. This side was the biggest headache. Passenger side was much smoother sailing.
