I have searched and googled a ton of stuff about this engine. I need to know what cylinder heads are on this 2006 chevy 2500 express van. I can get the heads for virtually nothing but I cannot read the head casting number in the van because its too far back to read. Does anyone know what head is on this motor? Any help is appreciated. Thanks very much.
