If you can have some torches handy it'll make things much easier....if the stuff has never been removed, it can be a pain...The heat makes things come apart easy...
The smog tube can be a mother to, it crimps and can be a pain...just hacksaw the freaking thing off if need be...reconnect with some hi-temp hose..
Have some long extensions and a swivel.. they make getting at the header nuts much easier...
Some Fel-pro 1415 gaskets and some stg 8 lockers and you should be done with those connections...
400.00...screw that...
