on my a429 heads the guide plate have a cut in the middle between the push rod slots so they could be adjusted to center the rockers on the valves they was this way when I got them for that same reason.They are not cut in two, just enough so they could be adjusted

Most serious type engines have "adjusted" guideplates ... this is not a small block Chevrolet; it takes a lot of checking as you go and a bit more talent to get it right.

I have done that on almost all of my 460 type heads to get everything where it should be.

I always get my motor built put it together then bring assy long block to my machine shop so they can measures my pushrod lenght. I know as nothing to do with the side to side movement. I think I might get a Jessel type cause I will have almost .800 lift am assuming.

That's good you do that cause I seen many of stock type build that are more than halfway off the valve tip at full lift. Is that what you where dealing with?
