Description

No longer will fans of the small block Chevy have to choose between vintage looks or modern cylinder head power—Trick Flow's DHC 175 cylinder heads give you both! These heads include springs for hydraulic flat tappet camshafts.



Made from premium grade, lightweight A356-T61 aluminum, DHC 175 heads feature the exterior styling and straight spark plug holes that deliver the nostalgic appearance of the original factory performance 186, 291, 461, 462 "double hump" or "camel back" castings that customers want. 60cc CNC-profiled combustion chambers combined with a state of the art valve job and CNC blended bowl work 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 Cast process that precisely duplicates the runner profile and performance levels of fully CNC-ported heads without the added machining cost. Ductile iron valve seats for use with unleaded fuel, stainless steel valves, bronze alloy valve guides, multi-angle valve seat machining, and decks and walls cast extra thick for increased casting strength and to provide extra room for porting round out the features.

These TFS-30210003 do not feature accessory bolt holes for 68' earlier setups, Search our store for TFS-30210007 with accessory bolt holes for 69' and later setups. Sold individually.
