All i have to add is that to make life easier in the future that you install the EGR system & simply transfer the whole KLDE vacuum system to the ZE while modifying whatever lines necessary to the correct places.
Shown in the picture is a KLDE head that has Circled in red the EGR port threaded block off that directs EGR to the manifold runners. On the early KLZE this port is threaded & open to the atmosphere. If you install the EGR valve you want to install the threaded plug in there. For the Late model KLZE heads that port is still there however it is blocked up with a ball bearing and needs nothing to change.
This keeps the EGR codes clear of the computer. However it does not make the EGR flow in to the motor when you are using the KLZE intake manifolds the port is simply blocked off and will not leak exhaust gas.
This leaves your options in the future open if you want to drill the ZE manifold & route the EGR to pass emissions if it is to become an issue some day for you.
I do my ZE swaps like that and never have any codes.
On another note that if you have no EGR installed and by some fluke chance you install a KLDE intake manifold on the motor your motor will not run because of a massive vacuum leak through the EGR passages.
