Why are you complaining about the blocks when the subject is about intakes and cylinder heads?
The majority of the racers are going fast with the OEM block both filled and unfilled.
It boils down to the quality of the machine work and the final finish of the cylinder walls.

So wall thickness and deck thickness have nothing to do with a better seal. And if so many racers are going fast, with stock blocks, why the need for aftermarket blocks.

And you want to limit it to that one subject.
