Tall Knuckle vs. Short Knuckle Spindles

I bought an E-body that came with front discs assemblies in the trunk. They are big bearing tall knuckle assemblies from a later B Body.

I would like to use them but have read that they may or may not cause issues with the upper ball joint not having enough room to move. I have bought QA1 tubular upper control arms as part of the package.

Anybody out there with real world experience running a tall knuckle spindle in an E-body?

thanks,
Rod
