I'm exasperated. I have a 1980 Chevy K10 with a 350 and all smog junk is long gone. I need to replace the exhaust manifolds. I dont want headers and want to retain the preheater for the carb. Do any of you have part numbers for applicable replacements?

Hooker makes some cool manifolds. Not sure if they have what you’re looking for, but a quick visit to their website ought to tell you.

I would find a set of ram horns if I were you, they are some of the best flowing manifolds produced and readily avaliable on cragslist FB market place etc.
If you dont need accessory bracket mounts I would do some of these. https://www.speedwaymotors.com/Smoothie-Rams-Horn-Exhaust-Manifolds-Small-Block-Chevy-Raw,94194.html

if the manifolds had the 8 smog tubes, I think they can be plugged with 1/8" pipe plugs.

The 63-66 corvette manifolds work nice. I had a set on my 72 GMC. I think you need two lefts (?)

There are also truck ram horns, but they have a smaller diameter (2") Depends what plans you have for your engine.
