I installed JBA headers a few weeks ago on my MY2000. I used new Toyota gaskets and locknuts. I did not use new studs but had to be very careful removing the hardware due to fairly heavy corrosion. I took my time - stopping whenever I felt too much resistance. I applied penetrating oil generously and let them soak then tried again later. I spent three days getting the old manifold off. After that it was a piece of cake. I'm very happy with the JBA header and Flowmaster exhaust combo. Good luck.
