67 camaro 502 headers

[seattle67]

Does anyone out there have a recommendation for full length headers that will fit a modified and fuel injected zz502 in a 67 pro-touring camaro? I will be running ~600 HP and would like to use full length headers with 2" or 2 1/8" primaries. I've been researching heavily, but am not confident that I'll have enough ground clearance for the lowered car or the necessary clearance in the engine bay.

Here are the vehicle mods that may influence the header selection:
- DSE Speed Kit 3 front end (tubular uppers/lowers, 600 steering gear, coilovers, etc.)
- IDIDIT steering column
- Vintage Air A/C and Frontrunner system (Gen IV)
- Keisler TKO 600 trans kit

I've been looking at the Hooker Super Comps, but have been told that ground clearance will likely be an issue. Lemons makes a great header that should fit, but are about triple the cost. Other good options? I've been waiting 15 years to bring her back to life, and we're finally at the assembly phase... and I want to get it right! Any help on what works would be appreciated.
