Trick Flows DHC 175 cylinder heads give small block Chevy enthusiasts a new performance option. No longer will anyone have to choose between vintage looks or modern cylinder head power with DHC 175 heads you get both!

DHC 175 heads are made from premium grade A356-T61 aluminum and have the exterior styling and straight spark plug holes that deliver the nostalgic appearance customers want. On the inside, 60cc CNC-profiled combustion chambers with blended bowl machining under the valves and small cross-section intake runners promote low-RPM torque increases and boost high-RPM horsepower. The runners are finished with Trick Flow?s superior Fast As Castprocess that precisely duplicates the runner profile and performance levels of fully CNC-ported heads without the added machining cost. In keeping with the vintage design, the heads are available with or without accessory bolt holes cast into them.

Other performance improvements include bronze alloy valve guides, ductile iron valve seats, and multi-angle valve seat machining on precision Serdiequipment. Plus, the decks and walls are cast extra thick to increase casting strength and provide plenty of material for future porting.

Trick Flow DHC 175 cylinder heads are available fully assembled or as bare castings. Sold individually.
