Dumb question about headers
"2003-2006 Chevy/GMC Yukon XL, Avalanche, 2500/3500, and Suburban, 2 & 4 WD"
"409 stainless steel; Ceramic Coated finish; 4L80E Trans Only"
After I google searched, they seem to fit the 8.1 motors.
Are the ports that different on those motors? Is there any reason they would not not fit on an LS1 camaro (2002) motor or the truck 4.8 or 5.3 motors?
