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 103 - Deck Tech
How to clean, inspect, and determine what you can do with your cylinder
head. Also how WHAT you do affects your oil system. There are many
variables at play when you make changes to your cylinder head deck from
your oil system, compression ratio, your valve timing and potentially even
disaster. 'best not to go that far with it. Watch this video and avoid it
if you're building your own 4g63 head.
The differences between this head and a 1g head are mostly related to port
sizes on the intake and Exhaust, and
different sized head bolt holes. The 7-bolt uses an 11mm bolt, and a
6-bolt uses 12mm. 1g heads have gigantic intake ports, but aside from
that, valve geometry, oil system functionality and the service limits are
all the same.

modifications for all generations of Mitsubishis, and specifically for 2g

Ultimate Head Test Part One, Intake Manifold Vs. .200 raised runner ProComp, Patriot Head
To follow the written and well photographed evaluation of this test go to
my website at www.headbytes.com and click the "Tech Blogs" tab and read the
comments and the final comment for the winner (a combination of Power,
structure, fitment and other perimeters of the test!!! This is the
begining of the three way test between the ProComp 190, Patriot 225, and
Brodix Trac One 215 cylinder Heads. First I had to determine the correct
runner height as many have written in that some of the China heads had a
problem of a typical intake manifold would not line up, and needed a
special gasket or plate to make them match up. In this first part of the
test I decided to put this problem to the test and decide which one had the
problem, if any.
