Todras,
The Vortech spec'd MSDS headers won't fit the SVT- due to its larger radiator. Non-SVTs, though are good to go. I guess the bottom line is that if you've got an SVT, it's either SC or headers, not both.
USMC,
Did your GT also have a returnless fuel system? Was it a Vortech SC and install kit? I would triple check to see if your SVT has the returnless fuel.... Not trying to be an a$$, really, I would hate to see one of us waste upwards of 3 grand because of incompatibility.
