I have a complete L29 I was planning on using until I read that thread and the one where the guy argued the dart block and merlin head 10k motor would run better than a stock L18.

I’m sorry, I thought you wanted to remove the EGR and install the plate. My bad. They all had EGR up until 2004 that I know of. I work for Workhorse/Navistar where we used couple hundred thousand 8.1L’s in our chassis from 2001 to 2010, which were of the heavier GVWR range of engines. Ours had EGR from 2001-2003. I suspect someone either did an engine swap on the donor truck or just removed it all together. What color are the valve covers? 2002 should have black textured valve covers. 2004 and later were bare aluminum. What about the exhaust manifold? Is the EGR port in the exhaust manifold cast over or does it look like someone plugged it?
I personally wouldn’t worry about it as you would need the EGR exhaust manifold which won’t fit your square body frame anyway.
