No longer will fans of the small block Chevy have to choose between vintage looks or modern cylinder head power—Trick Flow® DHC™ 175 cylinder heads give you both!

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. To keep with the vintage design, the heads are available with 69′ later or without 68′ earlier accessory bolt holes cast into them. 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.

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