I've had these headers sitting in my garage for a few years now and I want to use them in my sig car if they'll work. They are 440 headers, other than that I know nothing about them. Not in bad shape, a little in a couple spots but no rust. I measured and they are about 11.5" or so between the top of the 3" collector and the centerline of the exhaust ports, measuring straight up and down, not at an angle. Other than doing a test fit when I put the motor back into the car, is there any way to tell if they are even for my application?

Hmm, I *may* have answered my own question. They look a lot like a set of the hedman/summit cheapies, just with a cut flange. Pic pulled off summit's site:

the newer ones have the nice ball and cone at the bottom,which is nice with no gasket to blow out there
