Revised manifold bolt torque
The WOT-Tech 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 bolts: 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.

I include these directions with every manifold set. Any feedback is appreciated.
