They came with solid lifters but at least the later blocks were drilled for hydraulics. My '61 261 which is being rebuilt will have hydraulics. Someone else can give you more complete info. (I'm out-of-state now and can't check the info which I have in Montana. How did you come through the big wind yesterday?)
