i'm shopping for a header for my d21, auto tranny (i know, i know, i'm just making do...), with a 1990 ka24e (no plenum on the intake, throttle body directly on top of the intake; horizontal.). i've seen a header for a 1996-1997 ka24e. is there a difference in the size of the exhaust ports, bolt pattern and spacing, etc? more speciffically, can the 96-97 ka24e header be used on my 90 ka24e head? anyone know? all help is appreciated.
