Not really sure what you are asking but if you are asking if the rocker should be centered over the valve the answer is yes. Back in my stock hold-down days I’ve had to grind the tabs off the stock hold downs so I could shim the rockers over. I spend a lot of time doing this job once then it’s done for the life of the set up.
Good edit. Yes, by lateral alignment I did mean centered side to side over the valve. For the previous setup I used stock hold-downs and also ground the tabs off. Still looked jury-rigged but didn't show any unusual wear after 1300 street miles.
It looks like I can take .080 off each side of the aluminum hold-downs and that will put the rocker pad squarely over the valve tip. Time to break out the belt sander ;)
