Pushrod guide plates,Machine heads or not?

I've heard it and seen it both ways but should I machine the pedestals the same width as the plates for correct geometry or just slap them on? I think I know the expensive answer thats coming, Afterthought,with roller arms...

I found the answer to my question, clevelands have pedestals that lock down the rocker arms and dont allow them to shift,thus no need for guide plates. crane makes a set of push rod guides but when these things fails it usually results in a cracked rocker arm.

eventually went with scorpion pedestal mount platinums,no need for guides as long as my cam and spring pressure is not to agressive,which it isnt. putting them in this week.
