2.
Install a new gasket and high rise elbow to manifold. Tighten
bolts to 12-18 ft. lb. (16-24 N•m).
NOTICE!
Clean threads in the mounting holes are critical for
torquing of the riser bolts and the seal between the
riser and manifold.
Check all riser mounting holes in manifolds for debris or excessive
coating on threads.
• Bolts should screw completely in to hole by hand, if not, run
tap in holes to clear debris and coating.
• Use shop vacuum to remove debris from holes.
NOTICE!
The gasket mounting surfaces must be clean and flat
to insure the correct seal between the riser and mani-
fold. Carefully follow the steps below to insure a good
seal.
NOTICE!
Before proceeding place shop towels in the manifold
openings to prevent debris from entering the engine.
When the cleaning process is done, use a shop vacu-
um to remove debris from the manifold, riser and en-
gine.
3.
Clean the gasket mounting surfaces on both the riser and the
manifold.

Use spray on gasket remover to remove ALL traces of riser
gasket. Heavy scrapping with tools on gasket surfaces may
gouge surface, preventing proper seal.
5.

age to paint on manifold, riser or engine.
6.
Use 80 grit sandpaper and a sanding block, or equivalent to
smooth the gasket mounting surfaces on the riser and manifold.
NOTICE!
Do not use rotary power sanding tools, they may
leave a circular gouge in the surface.
