69380 454 SM465 headers mech clutch confirmation

[obijuank5]

I can not find the thread that says which headers fit a mechanical 84 and older k truck.

I search the part number 69380 and there used to be a thread with pics about fitment. Cant find it now.
Hedmans application chart says they fit 80s k30 with 454 sm465 4wd. These are going in a 79 k20 we are swapping a big block into.
CK5 says they fit?

also any suggestions on accompanying exhaust kits?


Thanks a million!

They should fit fine.

On my old 78 short box I swapped in a 454. I bought Hedman long tubes for it. I had a 465 in it.
I got no clue what the part number was...I built that truck over 20 years ago.

On the 77 I have now I swapped in a 454 and a 465 It has long tube headers as well but they where used and I don't know what brand they are.

Both trucks had mechanical linkage. Sorry that is all I got!?

That truck you are working on looks great! BTW. Good luck!

That might be it but that is almost exclusively small block talk.

I had some headmans and I have lots of pictures but I was running a th350 at the time.
