    Rated 5 out of 5 by from They fit perfect. Slipped right into my 78 TA Swapped a 6.0 ls and 4l60 in my 78 TA. These fit perfect. The flanges are really thick and the welding is really nice. For the price these are super nice stainless headers that sell for 600 at other places. Plus the oe style spark plug wires fit. Cant believe they slipped right in! buy some 18 inch collector extensions weld them on bam 40 ft pounds!
