Thanks for all the help. I agree whatever they tried to do, didnt work. I would've been more impressed if it had tho.

No. I was simply pointing out the second picture. On 1994 and 1995 engines GM stopped drilling the bolt holes in the block. This should be a 95. Someone actually removed them completely on mine. The intake should have nothing to do with that. I believe someone was experimenting with this engine.
I found this in a 95 z71. I am assuming this was an attempt to convert to roller cam? I say that because they worked on the block as well. But why would someone do this to the intake?
