Why would anyone wnat to run a 9.025 deck so far all the blocks I have machined no one has asked for a 9.025 deck block. Plus you not goint o finfd a GM block with both decks at 9.025 as I have never seen one yet.
I'm not too sure where the idea came from, to run a 9.025" deck. The idea was to relate a number for the shop to use that puts the decks where they need to be- and it has never been 9.025" in my experience. But then, it's never been a straight up 9" either.
It would be a nice luxury to have a blueprinted block for every engine. As long as the specs fall within the (rather "relaxed") GM factory limits, I generally call it good to go.
What is the story on the CNC'ed block above?
