im helping my brother build his high school baby........so far we have built the rolling frame and only need to find some headers that will fit......we are really trying to find someone who sales 1 7/8" primary's but these headers are hard to find for an awd/4wd truck seem like the biggest i can find are 1 3/4"..
we are trying to maximize the engine performance since it is a lq9/l92 headed engine.....any suggestions will help us get going on the project
