Taking a look at going to an Aluminum intake and headers to open up the Caddilac. MTS seels headers for big $$$ or conversion flanges to alter chev Big block headers, but then I found these on ebay: They seem to have fairly thick flanges at both ends, and shorty's are what I would need, does anyone have any info/feedback/opinions on thse headers? They only have chrome listed, otherwise I'd opt to save a buck and just go with the regulars. heres the ebay ad, theres about 10 of the same ad. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2469646139&category=33631 Thanks.
