This kit will clear factory knock sensors on Gen 3 engines. 2. For LS3 L92 and other heads have the rear ports blocked off. This block off is a simple aluminum plug. You can knock this plug out from the bottom out (if heads are off) with a punch. It can also be carefully drilled out as our corner blocks seal off the top flat surface. DO NOT enlarge the hole size overall. Care must be taken to not let aluminum chips fall into the head passage so we suggest multiple careful drills with vacuuming in between and possibly greasing the drill bit.
