Absolute worst heads Chevy ever made for the BBC. Those are the emissions smog heads, better known as "peanut ports".
You will also have a terrible time finding pistons for them that will work. They are neither a closed chamber head nor open. A true open chamber is 119CC.
Take them down to your local scrap yard and donate them, or use them in a tow truck.
They won't make HP, but they will make torque. Good for towing, not hot rodding.
The 14092360 casting is known as the "peanut port" head and are good for a peanut port. The 781 and 049 head have the large oval ports and can be made to make some decent power.
www.mortec.com is a good place to look for casting numbers.
