These just showed up this morning. They are amazing. I'm really glad I decided to go with the polished ones. They will look sweet. These are the LSx ones for the Speed Tech subframe. They will also work with stock subframes and they have them for SBC and BBC. http://www.speedtechperformance.com/...cat/cat230.htm One question for you guys though....I'm putting them on a new L92. Am I okay to run these when I first get the motor going. I've read before that you should not run polished headers for breaking in rebuilt motors as it will turn them blue. Not sure if that's the same with crate motors. Thanks and enjoy the pics.

See if you can find some beater headers (junk yard etc) if you are starting up a motor for the first time. They tend to run really rough and hot for the 1st 20minutes or so of run time. That's what I ended up doing, otherwise you risk discoloring or damaging any ceramic coating.
It's always a good idea to have a large fan blowing into the front of the car to help keep things cool during initial startup. Wiping down the headers with alcohol and a clean cloth just before startup will also help keep the tubes clean.
Thanks for all the comments guys. I'm really happy with them. I see that Stainless Works sell a compound that will take off the blue. As long as that works, I'll be happy.
I got them installed today. If you want to see more pics, check out my build thread. If you've ever needed a reason to do a LS swap, try installing a set of headers and you'll be sold. I didn't swear, throw a tool or smack my hand once. They go on so much nicer than small block headers.
If you're wondering how they sit in comparison to the subframe, they hang down just a bit
