Stock manifolds or aftermarket (Offy/Fenton) ?
There will be some differences in how they install. In any case, the gasket and port rings go first, then exhaust, then intake. If you are using the stock manifolds, you'll want to bolt them together at the heat riser first, then install. Replacing the bolts with studs helps as well, as they help hold the gasket in place. See the pic at the bottom of
this page for proper tightening sequence and torque specs.
