Head
Cleanup and
Inspection:
After receiving your heads they are cleaned
and inspected to see what repair work is
necessary. Some heads are unusable due to
corrosion or heat damage. If rebuildable, a
list is made of all the work required.
Valves are removed, seats checked, and cylinder
mating surface is inspected. Once the
core is passable it goes to the milling machine
for touchup....
Milling
process:
On the milling
machine there are a couple things I can do.
1) Mill the tops of the fins and clean up some
of the flashing and uneven surfaces for better
cooling
2) Mill the valve cover surface even -
not always needed
3) Mill the cylinder
mating surface - known as flycutting I can smooth
out the surface and match all three
cylinders. May require thicker copper head
gaskets for proper compression ratio
4) Mill
the intake area for a welded on intake tube - will
mate to William Wynne's intake
pipes.
Welding:
The main
welding procedure that I can do is to TIG weld the
aluminum intake manifold onto the intake
log. Not everybody wants this done as others
use the stock intake pad.
Spark plugs
holes:
If the spark plug holes are
damaged - or by request, TIME SERTS are
installed. I also provide a set of
copper spark plug gaskets to be used with
these inserts. It reduces the risk of
leakage due to the small stock
gasket.
Valve
Job:
There are some options in the valve
job. What I recommend is replacing all the
valves or at least the intakes with tufftrided
valves. If the springs and retainers are is
good shape they can be reused. However,
there is something to be said for replacing
everything. Remember that I have over 550
hours on a a good valve job with just new
valves. Guides will be replaced as necessary
or if requested they can all be new but I have
found that good stock guides work well. A
three angle valve grind and lapping is always
done.
Custom:
Everybody has different needs or wants so
the work require for one person is not the same as
for another. Customized milling and welding,
valve work and even painting can be done as per
request. Great care will be taken on all
heads and I will call you and tell you where you
stand as far as recommendations and
progress.
