BIG LT1 headers?
BIG LT1 headers? Wat does everyone use for BIG headers? I'm gonna need like a 1 7/8 set. Does anyone make them? If so does anyone know where I can find them and wat PN everything is? I know Kooks makes a set but those are stepped. Does anyone make a true 1 7/8 headers?

Because the primaries are so big, the bolt spacing of the traditional bolt pattern will cause interferance with the tubes. They use a 18* bolt pattern and require an adaptor that may need to be ported to match the size of your header/port. You need something along these lines:

Ok ok, so is this with ALL big tubed headers? or just the hedmans? Like if I went with a set of the Lemons headers would I have to do that also? Or should I just call Lemon and ask them?
You most likely would, it's more of a restriction set by the primary size interfering with those bolts cause of necessary clearances to spin the bolt and such. I believe some heads like the big-port AFR's can be ordered with the other bolt pattern from the get-go, but I'm guessing you already have heads with the standard bolt pattern.

I am also interested in a bigger header then the conventional super comp hookers. I picked up a set of bowtie Vortec heads 215cc intake and 84cc exaust. The exaust runners are raised like a LT1 head, so wouldn't you need to modify the exaust flange to fit the heads or are the headers made for LT1 heads.
Another vote for lemons. I have 2" primaries (LT1 but with SB2's) and they fit very well. I had to make some mods to the chassis but that was due to the width and layout of the heads and not so much the large tube size.
