'72 Cheyenne 350 Cylinder Heads #s
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

Re: '72 Cheyenne 350 Cylinder Heads #s
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.

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