Volvo Engine head porting/ matching exhaust
Gasket matching my Exhaust port on the
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

The Eastwood Engine Porting Kit can help your engine generate more power.
Watch the video.
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 Porting and Port Matching
Anthony @ DIYautotech takes you through the steps on how to port match (
gasket match) your cylinder heads. This is a fairly simple project that
may take you about a day, but will give you a cylinder head with high flow
High Flow = More Power

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:

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..
351W Cobra Motor Oil Issue Update
I have been working off and on trying to figure out why I'm having oil in
the intake manifold for this engine. I just ran it this week and took it
apart fresh after running and found the problem. Really unique problem and
I wanted to share it with everyone.

Volvo Engine head porting / port matching prep work !

Step two in the project :
Gasket matching is a good way to improve the flow in your head (engine
heads only) and to avoid the bad turbulences where they are not supposed to
be : between parts.
It's the first step in your porting job that you should think about ,and do
with your brain and hands.
The castings patterns are often quite "bad quality" (or i should say the
consequence of the application of a mass production process ) and it's the
way to start this kind of job.
