Product Description

TFS DHC 175 SB Chevrolet Cylinder Heads - Hyd. Roller

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!

Made from premium grade, lightweight A356-T61 aluminum, these DHC 175 cylinder 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, these heads are similar to 1968 and earlier with no accessory bolt holes cast into them. These castings feature a 60cc CNC profiled combustion chamber combined with a state of the art valve job. Adding in CNC blended bowl work under the valves and small cross section intake runners promote low RPM torque increases and boost high RPM horsepower with the proper valvetrain.

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 with decks and port walls cast extra thick for increased casting strength and to provide extra room for porting. 

PLEASE NOTE: These heads are not catalog items and are built per order. The lead times vary depending on the current schedule and available machine time. Understand that because of the nature and design of these cylinder heads, there will be no guaranteed delivery date. Plan accordingly.
