Most cylinder heads are identified in a general sense from simply looking at them. But just knowing the generic type of engine does not begin to tell the whole story. There are a wide variety of heads for most any given engine type and in many cases there's a lot of difference between them in their potential for performance. | Most cylinder heads are identified in a general sense from simply looking at them.

A big block Chevy (BBC) or small block Chevy (SBC) head is readily recognized by the majority, as are Hemi heads, small block Ford (SBF) heads, and depending on experience and engine preferences, others as well. | A big block Chevy (BBC) or small block Chevy (SBC) head is readily recognized by the majority, as are Hemi heads, small block Ford (SBF) heads, and depending on experience and engine preferences, others as well. | ||

Through the years, small block Chevy heads have been ID'd by the head's different end casting shapes. They don't usually tell the exact details like valve sizes but are useful for telling (at least potentially) a performance head from a non performance head. A casting identifier can differentiate between a large or small combustion chamber volume, also intake port volume, spark plug type (gasketed or tapered seat), whether they were used with a certain type of front accessory arrangement (short or long water pump for instance). | Through the years, small block Chevy heads have been ID'd by the head's different end casting shapes.

The most recognized end casting identifier of the SBC heads is the "fuelie", "double hump", or "camel hump". It got the name fuelie from the fact that it was used on optional high performance fuel injected SBC engines, mainly installed in the Corvette. The name fuelie is somewhat of a misnomer, however; the fuelie heads were used on carbureted engines as well. | The most recognized end casting identifier of the SBC heads is the "fuelie", "double hump", or "camel hump".
