SBC DHC 175 ALm Cylinder Head 60cc S/P Assembled

The Trick Flow SBC DHC 175 ALm Cylinder Head 60cc S/P Assembled is a high-flow aluminum cylinder head engineered for small-block Chevy engines seeking maximum intake efficiency. This pre-assembled head arrives ready for installation, eliminating the need for separate valve train component sourcing and reducing build complexity for engine builders working on performance platforms.

The 175 cubic-centimeter intake port volume is designed to flow high volumes of fuel-air mixture, supporting naturally aspirated small-block builds targeting mid-range to upper RPM power bands. The 60 cubic-centimeter combustion chamber supports compression ratios typical of street and mild racing applications. Valve specifications include 2.020-inch intake and 1.600-inch exhaust valves paired with 1.460-inch valve springs, delivering reliable valve control across aggressive cam profiles. Aluminum construction keeps overall engine weight low while maintaining thermal management characteristics necessary for sustained performance. This assembly format—with valves, springs, and retainers installed at the factory—eliminates critical assembly variables and reduces the risk of improper spring installation or valve seat damage during on-engine setup.

Engine builders and performance enthusiasts restoring or upgrading small-block Chevy platforms benefit from this head's plug-and-play nature. Whether supporting a street machine, weekend track vehicle, or classic car restoration, the DHC 175 delivers proven port geometry without the labor intensity of valve lapping, spring installation, and timing verification. The 29.68-pound weight reflects the aluminum construction, aiding overall vehicle dynamics and reducing parasitic engine mass.

Small-block Chevy cylinder heads are foundational components in the aftermarket performance ecosystem. The DHC series represents Trick Flow's commitment to direct-bolt compatibility and flow-tested port design. Buyers selecting this head can proceed with confidence in its fitment and factory assembly quality, knowing each valve train component has been installed to specification before shipment.
