Conversions & Hybrids - S&P early mounts header in 67 Camaro

I'm sure this question beaten to death. I did my 67 camaro ls1 like 5 years ago with s&p style mounts and like to get headers now. So what is a good fit headers stainless or regular? I want to make sure that I dont run into problem. Thanks for any info guys.
Thanks.

Stainless works headers work great with the S&P mounts.
