Just a question for the techs or anybody else. Will the 2004 heads with the fuel return lines on the outside of the valve covers be able to be fitted onto the earlier model Duramax's. I'm assuming the bolt patterns for the exhaust,intakes and head are still the same. Also is the EGR part of the head assembly or a seperate piece. Thanks Dave
