Sram Red Cranks

So i fitted some Sram red exogram gxp cranks to my 2013 Allez, thinking this would be compatible. I used this with a chris king bottom bracket to find there was a ~5mm gap once the cranks were fully torqued.
I put a 2.5mm bb spacer either side of the bb cups and the cranks then sat flush, but ever since setting it up the cranks have been creaking. I have changed the BB to a truvativ/sram model but the creaking still persists. I have checked all the usual suspects such as chainring bolts, pedals, seatpost, bars etc.
I also took it to the LBS and they said it was a BB compatibility issue. I am unsure whether it is or not because after changing the BB the creaking still persisted. I did note that the chainring bolts were originally over-torqued and snapped one as i took them out to grease them. Would it be worth changing them all to see if this is the cause of the problem?
Sorry for the long post!
