I've had them on my 68 C10 LS swap for 3 years with zero issues. As much as I hate China made stuff I just couldn't see spending $800-$1200 for US made. My LS is a small cam LS1 so not huge horse power. If I was running a big HP engine I would not buy the Speed Engineering headers. The best designed headers have the longest gradual turn down after the exhaust port. If you look at the SE header design they take a tight bend after the exhaust port.
