    they seem to be the most recommended for hp/tq, but are they a good fit?

    do they need any BFH adjustments after install?

    and do they burn plug wires?

    If you do a search on ls1tech.com, there have been a few posting about them lately. It seems like some guys are having fitment problems, especially on 4wd. Not sure if Dyantech corrected the fitment issues or not. Hope that helps.

    I'd peep at The Other Guys headers or Arizona Speed & Marine...I'd run TOGs if it were my truck.
