Chevy LT-1 Cylinder Head Full Porting Stage IV
This is the full blown Stage IV Max Street porting of the LT-1 Cross-Flow
Cylinder Head. Part One....In this we cover the begining to end of
unshrouding and polishing the combustion chambers. Thanks to Tom Kish for
the use of his heads and the extra time he allowed for me to film and
perform these mods, and his permission to display his heads and work
performed. This procedure removed 3cc of material, and blended the chambers
to discourage detonation. This is part one of three of mods to turn a
stock 170cc LT-1 heads into Edelbrock, AFR killers. The valve size remains
the stock 1.94 and 1.50 sizes. To follow more go to www.headbytes.com
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
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.
Cylinder Head Porting and Port Matching
Anthony @ DIYautotech takes you through the steps on how to port match (
gasket match) your cylinder heads. This is a fairly simple project that
may take you about a day, but will give you a cylinder head with high flow
High Flow = More Power
