Which headers to buy?

[Ethan0]

Wanting to buy some headers for my truck. It’s a 76 k10 but the thing is the engine is an 83 350 and I’m not sure if I should buy the headers that will fit the truck, the 76, or the the engine, the 83 350. Not sure if there are any differences between the 76 350 and 83 350 engines.
So should I be looking for headers for a 76 or 83? Or is there not much of a difference? Any help is appreciated.

Should be no difference between small block ports/flanges.

I would go with searching for a 76 K10, I know over the years with various transmission and transfer cases and emissions equipment that crossmembers changed. This generally changes where the headers hang and exit.

Okay, I was assuming the engines or exhaust ports wouldn’t be different but just wanted to be sure.
Thanks for the help!

There are so many out there, the flow tech listed above in the link are good from what I hear. It all depends on what you want to spend. The best ones I ever had were Doug Thorley Tri Y's but they cost a lot more than the flow tech headers.
