I am kinda new to this also but I looked into different headers and from what i have seen in pictures and in posts is the Thorley THY-133Y is the way to go. The Thorley part number is DTE-133Y and the THY-133Y is the summit part number for the same thing. I own the pacesetter long tube header on mine and i do not like the fit as it want to rub on the bellhousing flange and doesnt seat very well on the no.4 cyl part of the head. Hope this helps.
