HEAD SETS (HS)
Fel-Pro® Head Sets give technicians not only the gaskets the project requires, but the very best technology available. Head Sets are used for upper engine repair only, typically on a valve grind. They can be combined with a Fel-Pro Conversion Set (CS) to form a Full Set (FS) for the entire engine.
AD INSTALLATION SETS (HIS)
These sets are designed to save money by giving the technician the exact gaskets needed for installing an already reconditioned or fully assembled head. These sets do not include the valve stem and camshaft seals that aren’t needed, so technicians aren’t forced to buy parts that aren’t required.
CONVERSION SETS (CS)
Fel-Pro® Conversion Sets provide every gasket necessary for lower engine work. When combined with a Head Set, Conversion Sets can be used for a complete overhaul or as a Full Set.
PermaTorque MLS® Head Gaskets with Laser Weld
LaserWeld™ Stopper Layer Technology for stronger combustion sealing and decreased cylinder head lift.
Exclusive blue coating seals rougher finishes (up to 60 Ra).
LaserWeld™ is a sophisticated head gasket stopper layer technology that provides a precisely determined limit to the compression of the multiple layers within the PermaTorque® MLS gasket, while ensuring proper sealing stress between the cylinder head and block. This reduces head lift and bore distortion, prevents gasket damage, and ensures a superior seal.
These full-hard multi-layer stainless steel head gaskets provide the correct design for MLS-equipped vehicles and have many unique features that provide for a superior seal, including a unique aftermarket coating that accommodates less-than-perfect surface finishes up to 60 Ra (360 Rz).
The industry standard for no-retorque head gaskets, they feature solid or perforated steel facings, and precision stamped and formed combustion armors, and are available with the famous Blue Stripe® coating or with Printoseal® elastomeric sealing beads, as the application requires.
Ruggedly engineered, these head gaskets feature an impressive collection of exclusive enhancements that ensure superior performance and longevity under the toughest conditions and keep severe duty vehicles’ (like RV, commercial, and towing vehicles) engines sealed reliably.
