The Powerstroke Products PP-7.3LH-HDV (PP-7.3LH-HDVS) is a brand-new, fully assembled loaded cupless cylinder head engineered for 1999–2003 7.3 Powerstroke diesel engines. Built from a fresh casting rather than a remanufactured core, this head eliminates core charges and crack repairs while upgrading valvetrain stability. Powerstroke Products equips this head with precision-pressed valve seats, brand-new valves, and upgraded 155-lb heavy-duty performance valve springs rated for up to 4,500 RPM. Most importantly, it features an innovative cupless injector bore design where the injector cavity is cast and CNC-machined directly into the iron, completely eliminating the failure-prone brass/stainless press-in injector cups.

Cracked factory cylinder heads, valve float and reversion under high boost and elevated RPM, fuel entering the degas bottle from ruptured injector cup retaining compound, and coolant leaking into cylinders are what this head permanently solves. On stock 7.3 heads, thin brass injector sleeves are pressed into coolant passages; over time, heat cycling and pressure break the Loctite seal, resulting in chronic fuel-in-coolant contamination. By casting the injector seat directly into solid iron, this head permanently eliminates injector cups from the 7.3 platform. Paired with 155-lb valve springs, it prevents intake and exhaust valve bounce under high boost from upgraded drop-in or T4 turbos and aggressive tuning. It is sold as a single loaded cylinder head; two heads are required for a complete engine overhaul, and head studs, pushrods, rocker arms, and gaskets are sold separately.

It fits 1999–2003 7.3 Powerstroke Ford Super Duty trucks, Excursions, and E-Series vans.

• Single loaded cylinder head only (two required per engine)

Due to the increased seat pressure of 155-lb valve springs, pairing this cylinder head with upgraded heavy-duty pushrods (such as 3/8" .080" or .120" wall pushrods) is strongly recommended to prevent pushrod flex or valvetrain deflection. Thoroughly clean the engine block deck and chase all block head bolt holes dry with compressed air before installation. When dropping in standard HEUI fuel injectors, lubricate the injector body O-rings generously with clean engine oil; because the head is cupless, no injector cup sleeve tools or sleeve retaining compounds are ever used. Always torque cylinder head fasteners using heavy-duty head studs in the factory spiral pattern across multiple progressive stages to the manufacturer's final recommended torque specification.
