My brakes work but I am concerned about not running the front pressure valve. I couldn't find anything that says the corvette master cylinder has an internal valve built in.

Is this part of a front disc brake/power booster conversion Kit? This is almost the exact same set up as I got from Classic Performance Parts. They have a tech line that is great for figuring out these problems.
