'72 Cheyenne 350 Cylinder Heads #s - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does anyone know what the cylinder head GM number was on a '72 C-10 Cheyenne 350 4-bolt main? Or, how many GM numbers on heads were there? I was told that there are different sets of heads out there with different numbers. Thanks

There are alot of different heads that fit the small blocks. The heads won't determine if you have a 350 4 bolt main. I will guess there are at least 10 different castings that were used for the 350 engines.

Here are a couple pictures of the casting number. Let me know what you think they could be:

OK, 3998993 comes up as 1969-1974 307 or 350. Used for a truck or car, light duty.

Thanks To Much...I think it is 3998993 and is it possible to find one on this site?

Prolly just a run of the mill 1.94 head. Not many stock "performance" heads on trucks.
