It is listed for the Ford E-250 Econoline Club Wagon, E-350 Econoline, E-350 Econoline Club Wagon, F-250, F-350, F-53 Motorhome Chassis, and F-Super Duty, with fitment notes indicating cylinder head bolts are not included and replacement is recommended. The set uses composite sealing materials for the head and intake gaskets, along with perforated steel for the exhaust manifold gasket, and it is not a torque-to-yield application. This part cross-references FEL-PRO HS 8558 PT-6 and Ford E8TZ 6079-B for the same application. Mahle HS3978K is a practical choice when servicing sealing surfaces on compatible Ford engines and when a complete gasket set is needed for reassembly.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing worn or damaged cylinder head sealing components\u003c\/li\u003e\n\u003cli\u003eAddressing coolant or compression loss at the head gasket interface\u003c\/li\u003e\n\u003cli\u003eServicing intake manifold sealing surfaces during engine repair\u003c\/li\u003e\n\u003cli\u003eRestoring exhaust manifold sealing during top-end engine work\u003c\/li\u003e\n\u003cli\u003eSupporting engine reassembly after cylinder head removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify engine code and build date before ordering, since the listed Ford applications are limited to 1990-1992 coverage and one 1992 cutoff date through 2\/15\/92.
