The Vortec intake is bolted to the heads with a total of 8 bolts instead of 12, and they are at a verticle angle as opposed to being perpendicular to the head (the '87-'95's the center two on each side were angled slightly up from perpendicular to the head) Here is a pic of a Vortec intake manifold. You will notice the pattern of two bolts on each corner. Just a little FYI.

Captain, thanks for the info. I did some research and found the same information that you just provided. Wish I would have just waited for you to post! I have a true Vortec in my panel truck and after looking it over it is pretty clear that the heads in the 64 aren't Vortec heads. I will have to call the seller and ask about that! Knowing this might save me some frustration though because I have a serpentine setup off a 97 Chevy 1/2 ton that I was going to use but if I don't have Vortec heads I might not be able to. Any thoughts on that ?
