I agree with Mr.P. The location is fixed by the snap rings on the shafts.
Either the head valve location is wrong, or the rocker offset on those two is wrong. I would not run them that way with 0.800" lift. Swap them from another cylinder and find out which is wrong.
being that they are indy heads, I would not be surprised if it was the heads. I will move the 2 around and see if the problem follows them.
IF the guides were off we all know that you wouldnt
pull the heads off and send them back to see IF they
can or will fix them so you have to work around it..
you could have jesel move them or get 2 shafts with
just the mount holes and do your own snap rings grooves..
JMO.. I have the equipment to do it so I would do it myself
