I look at porting and polishing high performance heads,I been
building engines for 30 years, most of that time in research and
development,I explain in real simple terms air flows and velocities,these
308ci General Motors Holden heads have been transformed over 70 hours,I
show you all the do's and dont's,keep a lookout for the rest of the
rebuild vids, as we head into final assembly,especially dialing in
camshaft's,compression ratio's and everything else that makes internal
combustion engines cranky,Aussie Heads and Race Engines-One Man One Shop
Quick Tech Video: How to Degree Your COMP Cams® Camshaft
Installing a new camshaft often requires degreeing. This Quick Tech how-to
video from COMP Cams® is a step-by-step walkthrough on how to degree your
new COMP Cams® camshaft. But the Powerhouse® Products Cam Degree Kit can
be used with any brand of camshaft.

correctly. Measuring clearances, cam dial in, lifter preload setting etc.
COMP Cams How to Set a Valve Lash
Valve lash is the mechanical clearance in the valvetrain from the valve tip
to the rocker in a pushrod engine using solid lifters. Watch as COMP Cams
explain how to make lash valve adjustments with the proper tools.

Variable CAM timing is a concept that entails changing the camshaft timing,
as needed, depending on engine LOAD demands. This technology was impossible
just a few years ago, due to the state of the art electronics needed. The
latest Variable CAM Timing (VCT) systems are infinitely variable, meaning
they have no specified settings. CAM timing can be changed or varied
instantaneously across the whole range (ie. Plus or Minus 30 degrees from
normal). By varying the CAM timing, the ECM can regulate the power curve to
meet its own needs. On any gasoline engine, each RPM setting has an optimum
CAM timing setting, depending on load. Up until a few years ago engines
were set whatever the CAM lobes were machined at. With modern VCT, this
relationship can be varied, also varying the engine's power curve. Most
modern VCT systems do not control valve lift, but do great by simply
changing open and close timing points during engine operation. See how it
works here, with this superbly animated training video on automotive
technology and variable cam timing (VCT).

COMP Cams® Technology Explained: Cam Timing
The camshaft is often referred to as the "heart" or the "brain" of a
performance engine. This is due to the dramatic effect that valve timing
events have on a four-stroke internal combustion engine. This Technology
Explained video shows users the effect of each valve event, and how to
tailor those events to the requirements of their specific engine
application. Important cam timing terms such as Intake Opening, Intake
Closing, Exhaust Opening, Exhaust Closing and Overlap are covered as well.
