Headers question

I run that same Hedman Hustler header, but in the 1 3/4 primary (I didn't know about the bigger version at the time). I like them. My old 7qt low profile milodon pan had to be massaged with a hammer to make them fit. A few years back I switched to a Canton pan that clears the headers (but it has other issues).....long story short, they work well. My car runs low 10's @ ~3200#'s with ported Edelbrocks and a solid flat tappet.
