Cylinder Head 201 - Radius Cut Valve Job
This video covers the complete valve job process that your machinist might
perform. If the 100 series videos didn't help you identify and correct a
problem with your cylinder head, then this is the next step. This video is
brought to you with permission from my machinist in full 1080HD, and covers
cleaning up the head inside and out, preparation and setting up a radius
cutter, cutting all 16 valve seats, valve grinding, and spans 3.5 hours of
actual work in under 30 minutes. There's nothing like this anywhere else
THANK YOU BALLOS PRECISION MACHINE. Thank you for the professional
explanation and execution of a job excellently-done, and un-precedented
access to your facilities.
A valve job is done by re-grinding or replacing valves, and then having new
seats cut to match the faces of the valves you're using. There are several
different machines that might be utilized to achieve this result, but the
process is the same no matter how it's done. There are seat cutters that
utilize cutting stones. There are valve seat cutters with 3 separate
angles installed 120° out-of-phase, and there are single cutters with all
3 angles (radius cutter) that cut with one blade in one pass. The machine
demonstrated here is a Sunnen VGS-20 Radius Cutter. This machine (now out
of production) produces a gradual curved seat that's superior to the shape
of a traditional 3-angle seat. While a radius cutter does contain the 30,
45 and 60 degree angles, it does so without leaving any sharp edges between
My valve selection includes Supertech 1mm oversized nitride-coated
stainless steel undercut and back-cut intake valves, and 1mm oversized
Inconel back-cut Exhaust valves.
Inconel is a high-temperature alloy utilized in marine and forced-induction
performance engines that can handle more abuse than steel can without
melting. The other characteristics of the valves which are discussed
typically yield bigger gains in airflow than simply using a bigger hole and
a bigger valve.
Why I did this to a perfectly-good cylinder head:
I changed cams. Because the valves were previously recessed during another
valve job 9 years ago, my valve installed height was increased and this
raised the operating positions of my rocker arms. My new camshaft
selection dictates using the stock valve install height. The only
solutions to this valve install height problem are to either replace the
valve seats, or install oversized valves. I opted for the latter.

how they all work. Understanding how they work is critical in diagnosing

Well this was a fun one to make. I believe I covered everything but if you
feel I haven't please let me know in the comments below as well as any tips
you might have to add as well. I'm not trying to make a big deal about
"pound feet" or "foot pounds" I'm just trying to put that out there, the
important thing is that you get the proper torque and get the job done
right in my opinion, what you decide to call it is up to you.

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
