removing the EGR valve has nothing to do with the head gasket. Exhaust gas re-circulation is all the EGR system is, if anything no EGR reduces intake carbon deposits and slightly lowers intake temperatures. Honestly, any shop that blames a head gasket failure on an EGR system, probably shouldn't be changing head gaskets in the first place.
