Couple of things first: It depends on year of the engine and/or if your are installing an aftermarket aluminum manifold. The reason is pre '77 there were 16 intake bolts, '77 and later 12 intake bolts. If you have the "early" 14-bolt heads and are installing the 12-bolt manifold, it is not a problem. Most aftermarket manufacturers only sell manifolds for the 12-bolt pattern.
The torque sequences are a bit different between the two.
Let me know which type of manifold you are installing and I can sent you an e-mail with a torque sequence picture. If you don't have an e-mail, I'll spell it out here.
I checked your profile and you do have e-mail. I just sent you an e-mail with two images outlining the two bolt-pattern sequences.
Be mindful that aluminun torque specs, if you are installing an aluminum manifold, are lower that that for cast iron, 15 lbs max for aluminum IIRC. This was discussed over last couple of days, try a search to confirm.
Although following a torque sequence picture is the best way, the quick and dirty method I use at the track is to start in the center and work my way out, going from drivers side to passengers side in a zig-zag.....never had a bit of trouble.
Here's the correct pattern for the 16 bolt W manifold; you can extrapolate the 14 bolt pattern easily from this. Torque should be in the 20-22 lb-ft range
