Not sure how much the rise helps, but I installed a set of Flowtech headers (Had them installed with help of friends).

The tubes all clear, and nothing had to be dinged. The headers will still a pita to get in there. If doing it again, I would install the headers in the truck, then drop in the motor.

Arent Bigblocks 2 and 4wd specific when it comes to headers?



my flow techs that listed for 2x and 4x4 did not fit on the 2x truck on driver side,beat 50% of #1 tube almost flat and still did not fit flowtech = junk

the passide will have the tubes moved over for the front drive shaft to move up and down with chassis/driveline flex.

I would go with hedmans that are BB 2x spicific,IMHO
