HEADERSREX just sold an uncoated prototype set of car headers for $615, glad I wasn't home drinking beer when auction ended or they would have been more expensive. This was probably a marketing tool to establish pricing, and maybe they are close to manufacturing, but not yet listed on their interweb page. I'm waiting for headers to do an engine pull and rebuild with Mummert aluminum heads, I've been patient but really want to move forward (had the heads for months).
Any update on headers from ford-y-block John? there is a waiting customer base for real headers and I hope there is some competition to help with pricing, Y-blocks are an expensive motor to build and right now it's pretty much name your price on car headers.
