Re: Vortec Head Question

906 and 062 are the two you are looking for. They are virtually identical. The 906 casting had a "heavy duty exhaust valve seat" I think it was called....? but thats the only real difference.

IIRC the 906 casting was used in production vehicles, and 062 was an over-the-counter head. I could be wrong about that though.
