All headers are not equal
I have shown 2 pictures of headers. The 4.6 is not the same as 5.0 and 5.4. My mechanic said the headers that we ordered from relentlessperformance were a quality item. You should always contact relentlessperformance if you have questions about headers.
The picture for the 5.0 and 5.4 is the top without a gasket is the wrong one for 4.6 engine.
Notice the bolt pattern is different
