Im running bbk regular shorties on mine and have no problems. You just have to run 90* spark plug boots and modify a spark plug socket, but thats not too big of a deal. Dont listen to everybody else. If you just want to run regular stock shorties, the pass. side clears awesome but the drivers side needs some clearencing, I have one it you want it thats been modified to fit. My pass. side one got messed up in the wreck and when my car got done, I just put bbk's on it so I have a good drivers side one here.
