*PLEASE NOTE APPLICATION DETAILS BELOW!
This kit is for all 70-74 240Z-260Z's with E31 or E88 Cylinder Heads. For all later L-Series heads (N42, N47, P79, P90), follow the fuel system you are choosing. Regardless of which 70-83 Z you have, if you are using an N42, N47, P79, or P90, P90A head with a carburetor setup, you will need this kit. If you are using an N42, N47, P79, or P90 head with a fuel injection manifold, then you need the injection kit.

All L-Series heads also have 6 "spacers" that hold down both the intake manifold and the exhaust manifold/header at the same time. Check to see if these are worn and in need of replacing also.
