Riley Two Port and other "F" head OHV Model A/B
engines. Can be reshaped to fit Riley 4 ports.

Model A and B Ford 1928-1931

Model T Ford, all years.
HEAD GASKETS CAN BLOW.
THEY TEND TO GO MOST OFTEN IN HIGH STRESS HIGH TORQUE CONDITIONS. EXAMPLE:
LUGGING UP A HILL IN HIGH GEAR WHEN YOU SHOULD HAVE DOWN SHIFTED OR AT THE
BEGINNING OF A HILL CLIMB RACE OR DRAG RACE. |
Model A & B Fords 1928 to 1934
Model T Ford 1909 to 1927
Solid copper head gaskets are used in extreme high
performance, racing and problem applications.
Our normal stock is 0.062" thick. Copper is expensive
these days and availability is iffy from time to time. Cost of materials
jumps around constantly.
Special order thickness of .042" or 0.92" are available.
Normal stock composite gaskets are .062" thick Thickest gaskets
can help with reducing compression and seem to last longer.
These gaskets are 50 % annealed to soft. Additional
softness is often required. They can be heated in an oven at 500+
degrees (on a flat surface) for 4 hours and left to cool
(untouched) to room temp overnight in the oven.
Surface quality is steel wool roughened to help with grab.
Silicone sealer recommended.
While these gaskets will give a good compression seal,
they do not crush much and tend to weep water by capillary action through
machine grooves in the head and block if not sealed well.
Solid copper gaskets can be trimmed (ground) for
unusual combustion chamber shapes and over sizes.
We'd like to, but we can't
guarantee a head gasket. There are just too many variables. These gaskets are well made.
