When serious engine builders "blueprint" an engine, they'll "port" or
smooth-off rough head castings around the intake and Exhaust ports for improved, smoother air flow.
The engine can then "breathe" easier, resulting in greater power and

Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra
small-combustion-chamber head. Thats what it is. It's a J1 Elantra
cylinder head. Good luck finding another one like it. (read more)...
In Cylinder Head 106 I talked about the mainstream porting theories as they
are discussed. We looked at a cylinder head that I have thousands of
dollars of professional work performed on, and a bone-stock
second-generation head that I didn't port.
In this video I just might do something you haven't seen done before. For
some, that may be uncomfortable. The port and polish job I perform here is
what I think will work best for my current build. This is not an extreme
killer port job. What will be different here is where port textures are
concerned, I will be following the advice of a reputable source that will
remain un-named. You're free to port yours differently than I do in this
video, and I give you that out, around the 20 minute marker.
The Hyundai is far from being an ultimate-performance build. It's a $400
box of scraps with nothing but time invested. It's perfect for this video.
My finished product WILL be an improvement over what I had. I don't yet
have access to a flow bench. I still have an achievement to un-lock. As
far as you should be concerned with the techniques I employ... without flow
numbers there is no evidence of what this will do, but we will gather lots
of info from dynp sessions and drag strip time slips. If I could test it on
a flow bench, I would.
There are MANY, and when I say many, I mean thousands of flame war
mongering pirates floating around on rough seas with a hair trigger cannon
finger itching to fire if you port a head any differently than what the
herd mentality says to do while porting a cylinder head. I cover the herd
mentality because it has merit. It's been tested. Tried and true. But I
don't follow it to the letter of the law. I'm definitely not here to
de-bunk it. I would port a cylinder head differently for each build based
on how that engine was used. There's an extremely valid reason why
relating to air speed. It's not the texture of a port that maximizes the
effect of fuel atomization, but the velocity of the air running through an
x or y sized valve. The driving factor in this is the piston speed. I'm
not going to give you the technical information, but will refer you to
information about the Lovell factor. There's a better description of this
in the links below, and even a calculator to help you find your engine's
Why the Lovell factor is important:
Lovell gas factor calculator:
Only people who have flow testing equipment know for sure what really works
and have the capability to produce a perfectly-matched port job for the
ultimate performance build. Those guys know the definition of ultimate,
and THEY are floating below the water Aegis-class submarines ready to blow
your comment up if you don't know what you're talking about. They don't
care if you're an armchair mechanic or a herd of pirates. I will say,
they're zoomed in pretty close on me right now, and I'm expecting to take a
few hits. My work will be tested based on Dyno and drag strip performance,
and the results will be posted here. Fortunately, those kinds of videos
are a WHOLE LOT EASIER TO MAKE!!!
What i use to polish cylinder heads and intake manifolds
Join me on Facebook! www.facebook.com/omgitsmrmack
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..
Cutting Excess Guide from ProComp 210 SBC Head, custom Porting Combustion Chambers 4
Part Four of Port modificatins on ProComp 210cc aluminum SBC heads. Guide
over hang from installation and correcting the combustion chambers to
unshroud the spark plug is a big deal on these heads. China castings leave
a lot to be desired, but still with all the work you must do it is still
the bargin of the year and is a force to be reckond with when "bang per
buck" is needed. The base of the spark plug should not be exposed in the
chamber, and any valve guide "Overhang" will obstruck flow and create fuel
"sheer" which seperates vapor to droplets that wont burn. Most Big Name
companies will not take time to detial these issues as production cost
prohibit these mods, so have your local machine shop take apart your heads
and look for these problems before you bolt them on your prize engine.

Cylinder Head 105 - Valve Job Basics
Valves not sealing? Valves not bent? This is how you fix that problem.
In this video I outline the basic valve job procedure. Cleaning the
valves, cleaning the seats, cleaning the combustion chamber and lapping the
valves in to make a better seal.
Here I cover the process start-to-finish. It's the same exact process for
pretty much all non-rotary combustion engines. It takes patience and
perseverance to do this job, but anyone can do it. Reference your service
manual for measurements and service limits. Everything else that's not in
your service manual is in this video.
I apologize for not having broken busted crap to work with in this video.
It's more beneficial to all of you when bad fortune falls on me because it
gets well documented, and many people watching these videos are looking for
answers. If you have bent valves, you will discover it quickly once you
chuck one up in the drill. You'll see the face of the valve wobble around
while it spins. You'll see evidence of this damage on the valve seat. If
it's bad, you may see damage on the valve guides in the form of cracks or
missing pieces where the valve guides protrude through the head ports.
Give all that stuff a good visual inspection. ...and if you doubt yourself,
never hesitate to get a second opinion or consult a machine shop. They
will have access to expensive tools that you wont find in your average
Chevy LT-1 Cylinder Head Full Porting Stage IV
This is the full blown Stage IV Max Street porting of the LT-1 Cross-Flow
Cylinder Head. Part One....In this we cover the begining to end of
unshrouding and polishing the combustion chambers. Thanks to Tom Kish for
the use of his heads and the extra time he allowed for me to film and
perform these mods, and his permission to display his heads and work
performed. This procedure removed 3cc of material, and blended the chambers
to discourage detonation. This is part one of three of mods to turn a
stock 170cc LT-1 heads into Edelbrock, AFR killers. The valve size remains
the stock 1.94 and 1.50 sizes. To follow more go to www.headbytes.com
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.

"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.
