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
