Header size?
What are you guys using? My motor is a 5.3, fbody .500 cam and a LS1 manifold, backed by a TH400 and 9". Normally I would just stick with 1 3/4" in this application but I see a lot of different header sizes out there so I figured I would actually ask. Hedman makes a bunch of swap headers from 1 3/4 to 2" with stepped headers in between. The most I would do to this engine down the line is a head swap for some PRC heads and a 224R cam, so nothing crazy.
