I'm running 12" stroke 5150s with the stock lower bar pin in the stock location and homemade adapters on top. i don't remember off hand but for some reason 4 1/2" up seems right. so yeah since the lower mount is lower, you should have sufficient uptravel.
i have the exact same mounts for the rear (considering that is my picture lol). if it were me, i'd run the 12" strokes up front and 10" out back.
here is an idea
full flex
full bump (zero rubbing)
