Eric is right, of course. For the next time, here is how you can spot a Vortec. The intake is held to the heads with 8 bolts on a Vortec, yours has 12= prevortec. Also, the valve covers are held on by 4 bolts around the perimeter of the cover. Vortecs have 4 bolts down the center of the cover, in a line.

You might want to go back to that previous owner and "mention" his little bit of "misinformation" that he gave you. Makes you wonder what else he lied about.
