EGR passageway in heads

[jssblues]

where about would the passageway in the heads for egr be?????

On the end of the head closest to the firewall. There will be a crosstube connected between both heads which then continues on towards the intake.

Those are the thermactor or AIR pump ports. The EGR ports are the ports in the middle of the intake side surface, between the two center bolts for the intake.

These heads have it.....

These don't.......

What Joel said. The passages at the back of the heads are for the thermactor and smog system. The EGR ports are between the two center intake bolt holes on the head. Some are round like the ones in the above pic. Most of the ones I have seen on the Ford production heads look like a small intake port.

You could potentially have an exhaust leak if you've got bits and pieces of your thermactor system torn apart. Make sure the ports on the back off your heads are plugged and same for the small tube on the midpipe if you don't have to worry about emmissions.
