crank your tb's to see if u can get a bit more height to get away from the blocks perhaps ? or do what others do.... either bash the living crap out of the blocks to bend them in, or cut them on an angle and weld some plates over it.
i'm running a skyjacker lift + Smax keys (same height gainable by stock keys, these are just forged so more durable...) and run 295/70 R17's on AE rims that are 17x9 -11 offset (4.5..) and have quite a bit of distance away from the blocks as they sit now.... wont have to modify the blocks till i do Bodylift + 35's... try a crank.
