Sooooo I just lost 15 minutes of my life reading all 21 pages of this thread... Couple of comments... 16 wheel HP on HEADERS alone is what I would have expected. When I had my C5 Corvette this was exactly what we would have expected. We did a header/Z06 Intake/software tune and picked up 40 Wheel HP on an LS1. It's a known combo, so why anyone would poopoo headers producing anything over 20HP on their own is ridiculous. We would also have expected as others have stated that we'd be upgrading heads/cam/intake/tune later to make the header upgrade really shine. And this next comment is going to piss some of you off, but it's true. $825 is a STEAL for good quality custom headers. Bitching about the price per performance gained is sad, but seems to be the norm here on HybridZ. I'm doing my research right now and I'm trying to decide what route to go for headers on my LS1/heads/cam/ARE drysump build. I'd love to get a pair of these for my little 1976 280Z, but I don't want to wait a year, and I don't want to deal with unresponsive shops. So was this just a "You guys didn't meet the full agreed to group buy order of 20, so I'm not shipping the gaskets" or has this guy become a shop to deal with in these economucally tough times? Regardless, If anyone with a set isn't planning to use them now wants to unload them, Im' in the market for a set of heads. Feel free to contanct me. Mike
