Here are pictures I recently took for a friend in Australia who is trying to make a header or extractor for the U.S. Spec Lexus SC400. This is a pictorial gallery with brief descriptions.
Here is a picture of the driver side (LHD) SC400 header bolt on a 1UZFE long block.
Bottom view of the left header with O2 sensor opening
A closer look at the left header with O2 plug and the flange
Direct view of the header opening. Not back for stock flow, but will require larger opening with FI
Notice the mandrel bend steel tubes with moveable exhause flanges.
There are two banks of flanges per header. They can be turn upside down for turbo use.
The long block is rotated and the left header is sitting on it
Front view of the left header
More view of left header
Different angle viewing the O2 sensor. Its great for some of you trying to make a high flow header.
The driver side header is placed on the floor for better view.
The exhaust gas passes through here.
Still the left header
This is the right header or extractor with EGR outlet
Very similar to the left header
EGR opening from the right header

This where the O2 sensor goes on the right side
My decompress engine with ARP studs and .093″ copper head gaskets with special seal. This engine have about 40k miles. Its very low and in great shape. Got it for $450

This is a freelance site with no support by huge companies.
I have been doing most of the R&D and technical write-ups by
myself with my personal money and literally thousands of hours of my time. I have taken extra steps to
demonstrate in details how things are done. Currently I am
one of the few people doing Lexus V8 research and performance
enhancement. This effort comes from my personal love for
this wonderful engine. Most of the modifications are from
trial and error. There's no cookbook for 1UZFE
mods and its unknown territory for much of supercharger performance.
The parts, labor, web development and site hosting are
100% paid from my personal hobby money. If you feel my efforts help you
in any form, please do not hesitate to donate any amount of money
to support this site. You have no idea how much I and the entire Lexus and Toyota community appreciate it!
