The WOT-Tech 3100/3400 Competition Manifold Set requires the following torque procedure. Failing to follow these directions may result in a cracked manifold. This is a common issue even for stock manifolds when overtightened, but is even more important with the port work that has been done.

Lower Intake Manifold

Center bolts : First Pass = 62 lb in

Final Pass = 115 lb in

Corner bolts : First Pass = 115 lb in

Final Pass = 18 lb ft
 

Start with the center bolts, then corner bolts, then final tq on the center bolts, and finish with the final pass on the corner bolts.
 

Upper Intake Manifold

First Pass = 115 lb in

Final Pass = 18 lb ft

Start with the middle bolts, then the outside for the first pass, and repeat for the final pass.
