Product Description

TFS Twisted Wedge 11R 170 Cylinder Heads  (Small Block Ford)

These TFS Twisted Wedge 11R 170 "Street Port" small block Ford cylinder heads feature a refined combustion chamber and valvetrain design utilizing rolled and rotated valve centerlines. These 11R castings now have a shallower 11 degree intake and 13 degree exhaust angle for better flow through the usable lift range. The shallow valve angle also allows for more piston to valve clearance so your camshaft parameters can be more aggressive. The TFS TW11R 170 heads feature stainless steel 2.020" intake and 1.600" diameter valves with 8mm lightweight valve stems.

For 2016, the Trickflow Twisted Wedge head's patented rolled and rotated "twisted wedge" combustion chamber and valve location design is refined for more even more flow and horsepower with the new 11R package. You must specify chamber size when ordering a custom milled set.


- Fully CNC ported runners with CNC profiled 53cc chambers.
- Casting is CNC machined to give the new head a billet look.
- Modern LSx style lightweight 8mm valve stems
- LSX style 1.300" hydraulic roller dual valve springs
- ARP Pro-series 7/16" rocker arm studs
- Large diameter 1/2" heads bolt holes
- Optional titanium or tool steel retainers
- Fully CNC ported 170 cc intake runner volume
- Multi-angle and blended competition valve job
- Ductile iron valve seats and bronze alloy valve guides

PLEASE NOTE: These TFS 11R cylinder heads are not an "in-stock, catalog item" and are custom built per order. The lead times will vary depending on the current schedule and available machine time.
