What does 'no-retorque design' mean for this head gasket set?

A no-retorque design means that once the head bolts are tightened to spec, you typically do not need to go back and re-tighten them after the engine has run through a heat cycle. The steel core in this Fel-Pro gasket helps maintain clamping force without requiring a second torque pass.

What kind of sealing surfaces is this gasket designed for?

This Fel-Pro gasket set is engineered specifically for the repair environment, meaning it's designed to seal well even on surfaces that aren't perfectly flat or smooth. The proprietary coating and materials help compensate for minor imperfections.

What materials are used in the construction of this head gasket?

The gasket features graphite or reinforced fiber facing material combined with steel armor for strength and durability. It also includes a proprietary non-stick anti-friction coating.

Product Details

This Fel-Pro PermaTorque head gasket set is built with a steel core, which helps eliminate the need for retorquing head bolts after installation. That's a big deal in the repair world, especially when you're working on engines that might have imperfect sealing surfaces. Fel-Pro designed these gaskets specifically for those real-world repair situations, using proprietary materials and unique sealing technologies to ensure a solid seal. You'll find graphite or reinforced fiber facing material, along with steel armor, giving it the strength and durability needed for engine components.

A notable feature is the non-stick, anti-friction coating applied to the gasket. This coating helps seal small scratches and imperfections on the sealing surface, contributing to a more reliable seal right from the start. This set is designed to fit a variety of vehicles from the late 70s and early 80s, including models like the Buick LeSabre, Cadillac Seville, and Oldsmobile Delta 88, making it a popular choice for many classic engine rebuilds.
