Headers that fit with ridetech tru turn on 1969 Camaro

[SkeWest]

Hi. I've got a 69 Camaro with a sbc and I'm having issues finding headers that will fit with the tru turn setup. I've done some searching and found some that say the Dynatech #740-21310 will clear but the thread was a couple of years old so I thought I'd see if anyone had any additional info. I called Ridetech and they told me that people have had luck with Dynatech and Summit, but they couldn't give me any specific model numbers.

My setup is sbc with straight plugs, ridetech tubular a arms, muscle bar, and coil overs. M22, vintage air front runner, compact starter, and stock steering box.

Thanks for any help
