Your set does hang down low. I had Clifford headers for my Camaro & a manual trans. Not sure there is a Co that made headers tuck up close? Other than custom headers.
My headers got all smashed up for being too low.
Not sure if you considered Toms cast iron headers? I do not think you would loose too much power over headers. Plus headers seem to always leak, blow out gaskets etc.
Tlowe dyno tested a 250 w/headers & Langdons cast iron manifolds,,, but I think when the testing was done w/the cast iron manifolds is when the balancer/damper was failing therefore creating massive amounts of vibrations which absolutely kills power output.
