i have a 1993 suburban and im putting a ls1 in it, seeing if anyone has done this and knows whats the best headers to use for this fullsize

 

i have no personal experience with that conversion, but just from bodystyle, any ls1 header will most likely fit, because space is much more of an issue in an ls1 than a 93 suburban lol

as far as which ones, i prefer long tubes, and from everything i've seen/been told, you get what you pay for. cheaper headers work just as well (sometimes) but they wont last as long, tend to leak, etc. make sure you dont go cheap on the gaskets.
