VIN "X" Head Casting Numbers
I am looking to upgrade my 95 4.3L with the 96+ heads.
I know there are several different casting numbers and I want to make sure I get the best head from the factory, to work over real well.
If anyone knows of a resource to the casting numbers it would be much appreciated.
