77 c10 Big block headers

[Jacoblewis147]

I know this has probably been said 100 different times but..... looking for the best fitting long tubes that will bolt up nice to my 402 big block going in my 77 short bed. I've read a bunch of different things and no real true answers on what works. Running SBC 350 motor mounts and frame brackets.

I don’t have experience with using SBC motor mounts but I’ve had great luck with Hedman (long tubes) and Sanderson (shorty) headers.

My Hedman’s worked with both a 4 spd and TH400 with zero modifications. My Sanderson’s fit perfectly with a 4spd but I’ve never had a TH400 in this truck, I’ve read they may have clearance issues with the bellhousing flange.
