LT-7

After adjusting the rockers for zero lash tonight and putting the valve covers back on for the first time since installing the ARP headstuds, I cant get the covers to go on properly. It looks like the guide tubes are hitting the top of the studs and it ends up missaligning the cover. Has anyone had this happen or is there something majorly wrong? I think I may be able to cut the last 1/2 inch off the guide tubes or go to different covers maybe, but want some opinions before I go that route.
