I've been considering headers for a while. I want to go with a set of shorties for the LS3 and replace the cats. In past experience I have always had problems with header gaskets leaking at about 6k to 8k miles on them. Even if you checked bolt torque they still leaked. I was wondering if any body has expirienced this with thier camaro yet. I know we now have locking hardware and I even wired a set of bolts once and they still leaked after time. It is truly a job to replace gaskets and doing things twice without a mistake infuriates me. If a header manufactorer would produce a header with a flange heavier than 3/8" I would buy them tommorrow. I feel the 3/8" flange does not provide an adequate surface for the gasket and does warp ever so slightly from heat cycles over time.
