This one is the hyd roller block but the lifter bore is the same as the older non-rollers. On the later style blocks the lifter bore is taller and it has provisions for the tie bar retainer to bolt to.
I looked up the lifter diameter specs for the 1990 318/360 Dodge and according to Mitchell the lifter diameter for those is .9035-.9040. I don't have any info for the earlier version.
