Hey guys, i have a 1986 nissan d21 pickup with a z24i engine and manual tranny. i have two questions. anyone know where i can get a header for this motor and also i have an idle problem. it wants to idle at around 2000rpm constantly. i have now vaccum leaks found. any help is greatly appreciated

High idle might be due to a bad thermo element (might also be called a wax kit) located on the throttle body (water hose's going to it)
Thats what caused mine any way....
