Project Larry - 1964 Chevy

[Captainfab]

There are a few guys that think that any SBC head that requires center bolt valve covers is a Vortec head......not so. The center bolt valve cover heads started in 1987. The Vortec 350 was in production from 1996 thru 2002 and requires a different intake manifold than previous years. 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.
