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.
Engine Porting Kit & How To DIY from Eastwood
Buy It Here: http://www.eastwood.com/engine-porting-kit.html
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

Size Matters...Exhaust Collector Testing Part 1
BangShift.com is proud to be bringing you another episode of BangShift
Tech. In this episode you'll find us testing Exhaust collector length with the guys at
Westech Performance Group. Special thanks to Hooker headers for sending us
parts to tear up too.
EASY, HOW I LAPP & GRIND VALVES. THEY DONT TEACH THIS TRICK IN SCHOOL, ONLY OLDSKOOL.
Automotive technician since 1991 I show how I do a valve grinding job
(Lapping Valves) at home using a vacuum hose, drill & compound, don't over
think it and don't assume it cant be done. learn how and save money on your
project with out taking your cylinder head to the machine shop. Valve
guides must be in good shape ( with no significant play or bent Valves
before you perform this task, but this procedure works very well if done
with care & quality. Go get it! and God bless.
