'68 GMC - looking for BBC headers

[nikwho]

Hello guys,
I'm looking for a set of BBC headers for my '68 GMC. It's a factory SBC/std. trans truck with high hump. Has '80-'87 sub frame, Performance On-Line tubular engine mounts, drop spindles/springs. Just installed my '69 427 BBC, bored +0.030" to 433". It has a th350 transmission, but I plan to soon swap to a standard transmission. I've got nearly everything needed to go to a Muncie, so I was kicking around an M22 Rock Crusher swap. I love the way that those sound, plus, I think that a close close ratio 4 speed would be plenty fun and would gear accordingly. I may just pony up for a t56, as a 6 speed with overdrive also sounds nice. Anyway, I digress.

I was traveling down the road of modifying some '67-'69 Camaro BBC headers, but not really super excited about that path. I'm looking for some headers that will work with a BBC with the crossmember that I've got as well as the POL tubular towers. I want to be able to run a normal starter. I don't need huge primaries, but obviously want them to flow well. I was gonna run the Camaro headers, but they required some "adjusting" with a hammer to make them fit. They also required re-routing the primary tube that ran closest to the rear lower control arms. It's gotten involved enough that I want to see if there are good headers out there, in the $300-$600ish range that would bolt right in and work without denting tubes. I also want to make sure that they are going to cause issue when I do my standard transmission swap.
