Copper head gaskets are designed for use in all high performance applications
that require an extra measure of sealing or use very high compression.
Whether the application is Top Fuel, Circle Track or even Street,
there is no better sealing or more durable gasket material than solid
copper.
Precision CNC machined from a sheet of solid copper,
these copper head gaskets offer precise bore and stud hole alignment for a drop-on
fit. Being solid, they will not compress so there is no need to re-torque
and being solid they can not blowout.
Regardless of the type of use, these copper head gaskets are reusable
with proper handling and installation, for many engine rebuilds. These
copper head gaskets can be used with or without stainless steel 0-ring wire installed
in the block. They are totally acceptable for street use, as long
as a THIN bead of silicone is applied on both sides of the gasket
around ALL the water passage holes. All cylinder bores are totally
round and are not notched for valve clearance, except the Hemi and
TFX.
Copper head gaskets may cost more initially, but the improved
sealing and reusability make these well worth the investment in the
long run. Each set contains two ready-to-use "dead soft" copper head
gaskets. |

| O-ring wire is not
needed unless actual compression ratio is 14:1 and over. This
included blown and turbo engines. On engines using water cooling,
as opposed to dry Top Fuel and Alcohol, etc engines, a thin bead
of silicone must be applied around all water passageways on both
sides of the gasket. Nothing is needed to seal the compression. |
