There is a difference in the head gaskets of a DE and a Revup but I see Cosworth and Cometic listing them as 03-06 and only HKS seems to know the difference and lists only 03-05 non Revup gaskets and some resellers list HKS as 03-06.

So what are the aftermarket options for head gaskets for a Revup without modification?
