STEP 5: Grade 8 bolts are recommended for intake manifold installation. Grade 8 bolts are identified by (6)
hash marks on the head of the bolt. The torque specs supplied are for grade 8 fasteners.
STEP 6: A pre-assembly mock up is required to check the proper fit of the intake manifold to the long block
assembly.
Place the intake manifold on the long block without the intake manifold gaskets
The gap at the end rails needs to be .040” minimum.
This check insures that the manifold will not “bottom
out” on the end rails of the block. If it bottoms out, there is insufficient clamp load between the intake manifold
and cylinder head, and it’s likely that oil will be sucked into the intake runners
.
If the gap is less than .040” the end rails of the manifold will need to be machined.
This can be
checked with a scale or feeler gauges.
