That's exactly what everyone wants, and that's why there is no one answer.

We did a ls7 swap into 96 impala at work and I think they used kooks headers

Do u know if it 1 3/4 or 1 7/8 ?

Header size will depend on your setup. Every setup will react to every header differently. Some will respond better to smaller tubes or larger tubes, some to shorter primaries or longer ones.

There is no "hey what's makes the best power/torque for every setup so I can buy that one".

Summit 1-3/4 header kit $99 + Summit LSX flanges $60 = $160 longtube headers for anything
