When you consider what can go wrong when
even "minor" gaskets fail, you realize one thing:
THERE ARE NO UNIMPORTANT GASKETS!
Each one, no matter how small, plays a critical
role in vehicle sealing. Each has to be the best.
That's why you should be... 100% Fel-Pro.

gaskets provide the correct design
for MLS-equipped vehicles and
feature a unique aftermarket
coating that accommodates
less-than-perfect surface finishes.
PermaTorque The industry
standard for no-retorque head
gaskets features premium coatings,
facings and combustion armors.
head gaskets engineered for extra
strength under punishing conditions.
T-T-Y head bolts are particularly common on engines using
aluminum heads and/or multi-layer steel head gaskets.
These bolts are engineered to stretch within a controlled
"yield zone". Once they reach this zone, they spring back to
provide a precise level of clamping force over the entire
area of the gasket.
It's important to carefully follow the manufacturer's
tightening specification. Once T-T-Y bolts are stretched
beyond their yield zone, they become useless. Typically,
T-T-Y bolts are torqued to a specified limit, then again with
an additional partial turn to reach the bolt's yield zone.
It is recommend to never reuse a T-T-Y head bolt. Chances
are too great that it has already exceeded its elasticity barrier
and won't spring back to properly seal the engine.
Importance of Proper Torque
When a head gasket is installed between the cylinder head
and engine block, tightening the head bolts compresses the
gasket slightly, allowing the soft facing material on the
gasket to conform to the small irregularities on the head and
block deck surfaces. This allows the gasket to "cold seal" so it
won't leak coolant before the engine is started. The head
gasket's ability to achieve a positive cold seal, as well as to
maintain a long-lasting, leak-free seal depends on two
things: its own ability to retain torque over time (which
depends on the design of the gasket and the materials
used in its construction) and the clamping force applied
by the head bolts.
PermaTorque head gaskets are made with top-quality
materials and designed to remain resilient so they retain
torque, so no retorquing is necessary. (Some competitive
head gaskets alleged to be "no retorque" can lose as much
as 50 to 60% of their original torque after only 100 hours
