2002 Silverados were available with the 5.3. Is this a swap from a V6 to the 5.3?

I can't speak to a 2002 Silverado but I've used the Speed Engineering headers on a 68 C10 LS6 swap and 80 Camaro LS3 swap. Yes they are made in China. I used the long tube style. They fit well and zero leaks. If I was going for every last HP I would go with something else. The header tubes as they come out of the header flange could be a longer radius.
My builds are pretty mild so I struggle to spend $1200 on a set of headers.

The two sets I've had felt like they were made of tin cans. Pretty thin and they feel cheap. If your goal is to build the absolute cheapest truck in the world then yeah, add them to your build. Ther are not exactly top quality parts (but you surely knew that already).
