You can get them at the local auto store. They are a variety of thicknesses / material for different applications, usually about 5 sheets a pack for around $6.
A boost leak test starting at the compressor inlet tests the whole system. When doing the test, make sure to set the engine to 30* ATDC *so the valves aren't in overlap. Otherwise air might go out the exhaust
30* ATDC would be about 2 inches counterclockwise from the mark in the crank pulley, lined up to the 0* mark on the plastic cover.
Car's built on the inside, but not out :)
