There are casting shapes on the front of the head, but, without experience, this can be tricky. Best way is to pull off a valve cover, and check the number. You will see a big long GM number. The last three numbers, are the casting numbers. 461, and 462, are 1:94, small chamber. 186, and 041, are the same, but made later with alternator brackets, for mounting alt., ect. 441, is the same, but with larger chamber, to lower compression. The last one I do not remember the number, but, the front has a triangle on it. 1:70 intake, larger chamber, smog head. Useless.
