I was already running Hedman #68198 A-body/Chevelle headers on my 468", had the exhaust tucked up also. They fit like a glove. The Hooker 2455's are known to fit C10's too. The only problem is that most, if not all of the Chevelle 2 1/8" primary headers have one tube that goes out and around the framerail on both sides. I've found a few listings for 2 1/8" headers for 67-69 Camaro's that are all in the framerail, but I don't know if they will clear the clamshell motormounts I'm using. I had to trim the driver side engine bracket to clear the Hedmans, which was no big deal, but now everything is powdercoated and 'finished' so I'm really not into re-fabbing anything on the frame or crossmember.

Lemon's makes a 2 1/8" primary w/3.5" collector for 73-87 trucks, I just don't know for sure if the frames are that similar that the headers will clear everything on inside the frame. I know the front suspension crossmembers are the same, I'm just not sure about anything else.

Here is what I'm working with.
