"How To" Port polish an intake manifold
In this video I show you how to port polish an intake manifold. Remember to
wear your safety gear and take your time. The intake itself took roughly 2
hours to polish. Removal of the head is recommended before any grinding or
polishing to ensure none of the filings make it into the cylinder bore and
cause damage to the cylinder walls.

Nothing spectacular and quite boring to watch but quite tricky to do.
The point on this "process" is to align correctly the Exhaust port with the Exhaust manifold to allow gas to flow without
it can exit faster and let more
fresh air come inside the cylinder.
In the same time the shape of this port is important :
the very light conical shape is a good and reliable design for Exhaust.
the point is to grind very far to have a tight curve and not only grind to
Edelbrock RPM Olds 455 Head Porting
The scariest thing I ever did was port a set of new Edelbrock aluminum
cylinder heads. My first attempt at porting any cylinder head. I raised
the roof .200" and dropped the floor .040". It's best to leave the floor
alone or raise it by filling with epoxy. Porting kit by Mondello.

Just showing your guys how we go about polishing and getting the beautiful
finishes after its all said and done.. this method takes some skill.. some
might say i make it look easy.. at 14000rpm the grinder i use is not a joke
and has hurt people when they dont use it properly.. when the paper unloads
on a long rod it tends to bend the rod at a 90 degree angle and if the user
freaks out and does not hold it away and let it slow down then they end up
with a nice big sliced up arm or mid section.. i myself have bent a few in
my time and lucky for my i have a quick reflex and manage to hold it away
without hurting myself..
