I'm trading some old 350 parts I have lying around (that I'm not going to use) to someone for a pair of Mr Gasket longtube headers. He had them on his '88. I couldn't find them on jegs or summit, so does anyone here know anything about them? Either was I'm going to trade for them. Those 350 parts would have just rotted away anyways.

I plan on getting hooker longtubes next year, but for now I just need to get this 383 in. Thanks for any help given.
