We are developing an aluminum head for the 4.0L and It was a question that came up the other day. I was not sure of the answer.

Thank you again!!

EGR is only a function of header to intake manifold. If you make your aluminum head to HO intake specs, it will be easily adapted to a Renix.

We would like to make it emissions legal for as many years as possibly.

There will not need to be anything special on the head to accomodate the EGR. It is done between the exhaust and intake manifold only.

Base the head on a 0630 with the 0331's mounting for coil rails and you should be good for any 4.0L out there I believe.
