I had a set of Kooks on my 91 Stang with a 460 nad a C6, I also had a QA1 crossmember that really opened things up. The Kooks were 4 into 1 headers so each tube was installed individually and then connected to the others at the collector. I had lots of room to get to the plugs, no clearance issues except where my steering shaft came down from the firewall to the flaming river rack, had to put 1 small indention in the the header to clear the shaft. The Kooks are nice cause you dont have to pull the engine or loosen the motor mounts and pull the engine up or side to side. just slide each tube in and bolt to the heads.
