New to the site. I am swapping a 88 C1500 to 6.0 and 4l60. All the headers I am finding say they will work on 2wd only. Have any of you guys used the 2wd headers or is there just some modifications to make them work or is there headers that are specific to 4wd? I plan on using 4L60 w/ transfer case from later model. This is going to be a relatively stock engine swap other than headers and tune. It will be a daily driver. Any help would be appreciated.
