I am getting rid of all my smog stuff on my 89. I have a few quick questions. One is how can i block off the holes in the back of hte heads. Also how can i block off or at least make it so the egr doesnt work. For now thats all i have. Thanks
should be able to screw a bolt into the holes but i dont know what size i would guess a 9/16"x1/2" NC thread bolt will work..you may have to use a 1 inch bolt with some washers don't think you will be able to find the 1/2"....
