what valve covers work with roller rockers?1990 5.0.I'm using the 4" but I am having problems with the bracket for the gas pedal hitting the covers(I do have the 1" spacer installed).People are telling me that the ford Motorsport covers will not work with EFI

 

I have them on my car with a 1/2 inch intake spacer, still fits under the stock hood. The throttle cable will in fact hit, but I was able to fab up a solution. You will lose your cruise control if you do it my way (mine never worked anyways). What I did was to grind off the little nub that the cable attaches to and weld a new one on so the cable attaches on the top of the linkage. You will need to do some trimming on the throttle cable bracket, but it can be done.
BTW where in IL are you? I am in Lockport

 

I'm in Villa Park, Lombard area
