valve cover trouble!

I just got my engine back from the builder! The heads are edelbrock 360 alluminum heads with PRW SS roller rockers and shafts. I went to put on my new edelbrock elite valve covers and the holes didnt line up! i got playin with them and it looks like one end of the rocker shaft is hitting the inside of the cover. has anyone come across this before? what shold i do? I do have a set of cheepo stamped steal covers and they fit fine but i was told they will most likely leek all over my nice new engine so i bought these alluminum covers.
