STEP 2: Check port and gasket alignment to intake manifold and cylinder head.
Some aftermarket intake
manifolds do not match Ford Performance cylinder heads. Position the gasket on the manifold where the
locating tabs (beneath the water cross over holes) will contact the head gaskets.
STEP 3: Inspect intake manifold for debris, and make sure it’s clean.
Check all threaded holes and tap deeper if
necessary. Check the carburetor/throttle body gasket alignment. Also look at the gasket surfaces for nicks
and damage, raised surfaces on the flanges can prevent sealing. Minor raised imperfections can be repaired
by wrapping a sheet of 320 grit wet/dry sandpaper around a flat block and lightly sanding the surface (do not
be too aggressive as this will cause the surface to become uneven). If installing a used intake manifold it is
not recommended to dry blast it to clean it. The media will become imbedded and eventually fall out with heat
cycling of the engine. If the manifold is being transferred from a “failed” engine, be sure to inspect all
passages for any debris that may have been lodged from the previous engine.
STEP 4: Test fit the carburetor/throttle body and actuate the linkage. Check to make sure the throttle blades
do not contact the manifold.
