Bowtie 359 head casting problem help

Hello from Australia,
I am looking for someone with a bit of knoledge with the 359 casting bowtie alloy head.
I have recently purchased a set of these heads & after carfully looking at both heads(ported second hand) I have noticed that where the jesel rocker pedistal mount is on one head it is .250 higher than the other, also where the head bolt in the same area is, has been raise .500 higher.
My question is which head is better if any?
Is the higher raised one a later casting & a revision?
Any help is appreciated.
Matt
