193 heads on a Carbureted Chevy 350

Postby Coriolanus on Fri Oct 14, 2011 8:51 am

Anyone ever use 193 heads on a carbureted Chevy 350? I'm hearing the flow of the 193 heads is poor and they should not be taken over 5000 rpm.

I don't remember, are these the Swirl Port Heads? If so they are a bottom end truck head, and I've seen many of them cracked, unless they are the heavy duty truck head with the 3/8 exhaust valves and hardened exhaust seats installed from the factory. Those were less likely to crack but flow even less due to the 3/8 exhaust valves.

If your just looking to build a low end daily driver they should work fine.
No car yet, but I'm working on finding a Malibu Wagon, well lets just say trying to find a G-Body wagon.

I'm not looking to race or anything like that. I would like to build a car for going to work and cruising. My engine has an 880 casting block number and the 193 heads. With the quadrajet, I should get good fuel economy.

Thanks, I will. I would hate to have to remove the 191 heads on the other block. I hear they crack when removed.
