Hello, newbie! HEADERS WANTED!

Hello everyone! I am new to the forum and want you all to know that you'll find me here often. I just recently dropped my transmission out of my 1989 s-10 Blazer 4x4 v6 4.3 and I will soon be bugging you all for tech info during my re-building process of my baby!

While I am here and since my transmission is already yanked, where can I purchase a nice "factory type fit" set of headers for my beast? Can I find a set of headers to fit my chevy with the o sensor hookup?
