Our supplier is currently out of the stainless steel headers, so for the time being we will upgrade your order to ceramic coated headers for no additional cost.
Whistle go WHOOP WHOOP. We have tried and tossed many different types of headers to find something that fits the LS engines, clears the scouts narrow frame but not so close that there's excessive heat transfer to the oil pan. These are the only ones we have found that have quality construction and fit the task.
Install tip: torque header bolts to 18 lb*ft. After driving and getting headers up to operating temp, re-torque to 18 lb*ft.
