I am in the process of installing the V8 engine in my van and have been looking for some replacement EGR valves that screw into the front of the intake mainfold. Are you able to buy these new and if so from where? 061020141843.jpg The parts I am looking for are the 2 "valves" that screw into the front face of the intake.

This van is equiped with an inline heater tap. See the photo attached. It looks like an after market part. Where is the tap surposed to be located?
