Make sure to tighten evenly the bolts on theheader flanges in a cross sequence pattern similar to the rocker covers. Helps to tighten them up evenly and avoid leaks.
After running the engine for awhile recheck them for tightness, and look for exhaust leaks.
Do not put a pipe clamp on the front slip joint where the passenger side collector pipe connects to the remainder of the header.....no image to help explain (sorry) as you need this free to move under thermal expansion. Seen some posts of this connection clamped by some guys.
Good luck and enjoy the reduction in turbo lag.
