Boss 302 Heads Same As Cleveland Heads?

ken5_0 · August 19th, 2006, 12:47 AM

is there anything that makes them different? is there anyway to tell them apart?

At a guess I would say yes, they are the same. The boss is a cleveland motor. But I really don't know. I will see if I can find something on it at the house.

I have found that the water passages are alittle different. And there is no stamp under the valve cover. But the valves are the same. At least on the 70 boss comparred to the cleveland. Any thing else? I bought a boss 302 shortblock and dont know what combo to use. I really dont care about the originality I just want to make power. I can buy a "crossboss" from a guy but he doesn't have the carbs. So these would just make a nice paperweight without the carbs!!! Any combo ideas?

The two 351C head types call for two types of pistons--one for a closed-wedge chamber and another for an open-chamber design. The 351C-4V piston is the same basic slug used in the ’69-’70 Boss 302 engine because the Boss head is virtually the same as the 351C-4V head except for water-passage differences. (The ’69 Boss 302 was actually the first application, from the factory, of the 351C-4V heads on a Windsor block
