Well, since noone else has posted their knowledge, I will toss in my 2 cents.

I got hold of a set of gt-40p heads (with the 3 bars) from a fellow who had some basic porting work done to them. Now I went in to further port them. I noticed that there were no egr bumps but there were little recesses where the bumps would have been. These recesses did not have the holes in them however and neither were there any front and back injection holes on the head faces.

So if you dont have egr bumps but have the recesses without holes in them then that, I guess, is what they are supposed to look like!
