I just bought a 5.3 LS salvage yard pull out for my 85 Cutlass Supreme. I am doing a head port job, cam upgrade, and carb setup with the engine. What swap mounts are you guys using for the g-body? I'm having a hard time finding the right ones. What full length headers will fit in a g-body? Guys have told me ls1 camaro headers will, and other guys said that I have to get specific swap headers. Thanks
