Inkjunkie,
In reality I prefer to modify the stock K -member to meet my needs. I have used Alterkation on a "street car" and found their unit OK, not great but OK.
As far as headers go I use the latest and greatest aftermarket aluminum race heads out there and my engine builder likes to port them to excess so I have no choice but go the custom route. I get my flanges lazer cut to match the exhauset port size/configuartion and I buy a tube kit fab up the headers myself. I had a set done a few years back by a reputable builder and they were good but a little too pricey and it took forever to get them from the builder. 2 1/4 I.D. stainless tube is about a big as I want to go.
1/2 hour to take a set of headers out? That's outstanding!!! My best time is about two days. LOL!!!!
