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 To Clean The Carbon From Top Of Pistons | Using Only Household Products
VISIT THE SITE TO SEE ALL PHOTOS AND VIDEOS ON THIS:
After pulling the GT40 heads from the 5.0 roller motor I discovered that
the tops of the pistons were coated in a thick layer of black carbon
buildup. The cylinder walls (bores) were in great shape with no gouges or
burrs. This left me with 2 options. Option 1 was to disassemble the entire
short block and replace the pistons and parts that were essential after
short block disassembly. Or Option 2 was to try and clean these up and
freshen up the cylinder walls. I chose option 2.
I started by spraying the piston tops with the bathroom cleaner and I let
it soak in for about 10 minutes. Next, I took an SOS or Brillo pad and
soaked it in rubbing alcohol. I started to scrub and scrub until the carbon
began to come off in places. This is a vigorous process that does require
some old fashioned elbow grease but in the end the results are well worth
it. Once all of the carbon was relatively gone off of the flat areas of the
piston I broke out the air grinder with a brass brush for the valve reliefs
The air tools are not essential if you want to take a little extra time
with a brass bristled hand brush. Whatever you do, only use brass! After
all of the carbon was clear I used the steel wool wet with alcohol and
wiped down the cylinder bores and made them shine like new again. I gave
the pistons a final rinse with alcohol and then vigorously oiled the
pistons and the cylinder walls to ensure no surface rust would appear. I
also sprayed them down with Ballistol (gun cleaner all natural)
Anyone can do this with a little time and patients. Just take your time and
you'll love the results!
